+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+ - Added GC_finalizer_mem_freed, and changed some of the code that

+   deallocated by finalizers essentially needs to be counted as reclaimed
+   by the GC.  Otherwise there are cases in which the heap can grow

+ - Integrated Adam Megacz patches to not scan dynamic libraries if
+   we are compiling with gcc on win32.  Otherwise we need structured
+   exception handling to deal with asynchronously unmapped root

+ - Integrated Anthony Green's patch to support Wine.
+ - GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several
+   places, including gc_cpp.cc.  (Thanks to Wink Saville for pointing
+   this out.)
+ - Integrated Loren James Rittle's Alpha FreeBSD patches.  In
+   response to Richard Henderson's suggestion, these also
+   changed the declarations of symbols like _end on many platforms to

+   for pointing these out.)  Fix C++ comments in POWERPC port.  Add ARM32
+   incremental GC support.  Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux,
+   this time for real.  Use va_copy to get rid of cord printf problems
+   (finally).
+ - Close file descriptor used to count cpus.  Thanks to Jeff Sturm for
+   pointing out the omission.
+ - Don't just drop gcj free lists in GC_start_reclaim, since that can
+   eventually cause the marker to see a bogus mark descriptor in the 
+   dropped objects.  The usual symptom was a very intermittent segmentation
+   fault in the marker.  This mattered only if one of the GC_gcj_malloc
+   variants was used.  (Thanks to Michael Smith, Jeff Sturm, Bryce
+   McKinley and Tom Tromey for helping to track this down.)
+ - Fixed Linux and Solaris/64 SPARC configuration.  (Thanks to David Miller,
+   Jeff Sturm, Tom Tromey, and Christian Joensson.)
+ - Fixed a typo in strdup definition.  (Thanks to Gerard A Allan.)
+ - Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S.
+   This is needed on Linux.  I'm not sure whether it's better or worse
+   on Tru64.
+ - Changed gc_cpp.h once more to declare operator new and friends only in
+   a Microsoft environment.  This may need further fine tuning.  (Thanks to
+   Johannes Schmidt for pointing out that the older code breaks on gcc3.0.4.)
+ - Don't ever override strdup if it's already macro defined.  (Thanks to
+   Adnan Ali for pointing out the problem.)
+ - Changed gc_cpp.h yet again to also overload placement new.  Due to the
+   C++ overloading rules, the other overloaded new operations otherwise hide
+   placement new, which causes many STL uses to break.  (Thanks to Reza
+   Shahidi for reporting this, and to Matt Austern for proposing a fix.)
+ - Integrated cygwin pthreads support from Dan Bonachea.
+ - Turn on DYNAMIC_LOADING for NetBSD.  (Thanks to Krister Walfridsson.)
+ - Changed printing code to print more complete GC times.
+ - Applied Mark Mitchell's Irix patch to correct some bitrot.
+ - Clarified which object-printing routines in dbg_mlc.c should hold
+   the allocation lock.  Restructured the code to allow reasonable object
+   printing with -DREDIRECT_MALLOC.
+ - Fix the Linux mmap code to always start with 0x1000 as the initial hint.
+   Minor patches for 64-bit AIX, particularly to STACKBOTTOM.
+   (Thanks again to Jeffrey Mark Siskind.)
+ - Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict
+   with a system header. (Thanks to Philp Brown.)
+ - Cause win32_threads.c to handle an out of range stack pointer correctly,

+ - Integrated Bo Thorsen's X86-64 support.

+   (Thanks to H.J. Lu and Hiroshi Kawashima for resolving this.)

+   And __data_start doesn't seem to get defined correctly of the GC
+   library is loaded with LD_PRELOAD, e.g. for leak detection.
+ - If the GC_find_leak environment variable is set, do a
+   atexit(GC_gcollect) to give us at least one chance to detect leaks.
+   This may report some very benign leaks, but ...
+ - Addeded REDIRECT_FREE.  It's necessary if we want leak detection with
+   LD_PRELOAD.
+ - Defer printing of leaked objects, as for smashed objects.
+ - Fixed process and descriptor leak in GC_print_callers.  Try for
+   line number even if we got function name.)
+ - Ported parallel GC support and thread local allocation to Alpha.
+   Not yet well-tested.
+ - Added GC_DUMP_REGULARLY and added finalization statistics to GC_dump().
+ - Fixed Makefile.am to mention alpha_mach_dep.S instead of the defunct
+   alpha_mach_dep.s.  (Thanks to Fergus Henderson.)
+ - Incorporated a change to new_gc_alloc.h, suggested by Johannes Schmidt,
+   which should make it work with gcc3.1.  (I would still like to encourage
+   use of gc_allocator.h instead.) 
+ - Use alpha_mach_dep.S only on Linux.  (It's not clear that this is
+   optimal, but it otherwise didn't build on Tru64.  Thanks to Fergus
+   Henderson.)
+ - Added ifdef to guard free() in os_dep.c.  Otherwise we get a
+   compilation error on Irix.  (Thanks to Dai Sato.)
+ - Added an experimental version of GC_memalign to mallocx.c.  This can't
+   always work, since we don't handle alignment requests in the hblk-level
+   allocator, and we can't handle arbitrary pointer displacements unless
+   GC_all_interior_pointers is enabled.  But it should work for alignment
+   requests up to HBLKSIZE.  This is not yet documented in the standard
+   places.
+ - Finally debugged the OSF1/Tru64 thread support.  This needs more testing,
+   since I needed to add a somewhat unconvincing workaround for signal
+   delivery issues that I don't yet completely understand.  But it does
+   pass my tests, even in parallel GC mode.  Incremental GC support is
+   disabled if thread support is enabled, due to the signal issues.
+ - Eliminated name-space-incorrect definition of _cdecl from gc_cpp.h.
+ - Added GC_debug_malloc_replacement and GC_debug_realloc_replacement
+   declarations to gc.h.  On IA64, this is required for REDIRECT_MALLOC
+   to work correctly with these.
+ - Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format.
+
 To do:
+ - --enable-redirect-malloc is mostly untested and known not to work
+   on some platforms. 
+ - The win32 collector ends up tracing some (most?) objects allocated with
+   the system allocator, in spite if the fact that it tries not to.
+   This costs time and space, though it remains correct.
+   We need a way to identify memory regions used by the system malloc(),
+   or an alternate way to locate dll data areas.  A very partial
+   workaround is to use GC_malloc_atomic_uncollectable() instead of
+   the system malloc() for most allocation.

+<TITLE>Using the Garbage Collector as Leak Detector</title>
+</head>
+<BODY>
+<H1>Using the Garbage Collector as Leak Detector</h1>
+The garbage collector may be used as a leak detector.
+In this case, the primary function of the collector is to report
+objects that were allocated (typically with <TT>GC_MALLOC</tt>),
+not deallocated (normally with <TT>GC_FREE</tt>), but are
+no longer accessible.  Since the object is no longer accessible,
+there in normally no way to deallocate the object at a later time;
+thus it can safely be assumed that the object has been "leaked".
+<P>
+This is substantially different from counting leak detectors,
+which simply verify that all allocated objects are eventually
+deallocated.  A garbage-collector based leak detector can provide
+somewhat more precise information when an object was leaked.
+More importantly, it does not report objects that are never
+deallocated because they are part of "permanent" data structures.
+Thus it does not require all objects to be deallocated at process
+exit time, a potentially useless activity that often triggers
+large amounts of paging.
+<P>
+All non-ancient versions of the garbage collector provide
+leak detection support.  Version 5.3 adds the following
+features:
+<OL>
+<LI> Leak detection mode can be initiated at run-time by
+setting GC_find_leak instead of building the collector with FIND_LEAK
+defined.  This variable should be set to a nonzero value
+at program startup.
+<LI> Leaked objects should be reported and then correctly garbage collected.
+Prior versions either reported leaks or functioned as a garbage collector.
+</ol>
+For the rest of this description we will give instructions that work
+with any reasonable version of the collector.
+<P>
+To use the collector as a leak detector, follow the following steps:
+<OL>
+<LI> Build the collector with -DFIND_LEAK.  Otherwise use default
+build options.
+<LI> Change the program so that all allocation and deallocation goes
+through the garbage collector.
+<LI> Arrange to call <TT>GC_gcollect</tt> at appropriate points to check
+for leaks.
+(For sufficiently long running programs, this will happen implicitly,
+but probably not with sufficient frequency.)
+</ol>
+The second step can usually be accomplished with the
+<TT>-DREDIRECT_MALLOC=GC_malloc</tt> option when the collector is built,
+or by defining <TT>malloc</tt>, <TT>calloc</tt>,
+<TT>realloc</tt> and <TT>free</tt>
+to call the corresponding garbage collector functions.
+But this, by itself, will not yield very informative diagnostics,
+since the collector does not keep track of information about
+how objects were allocated.  The error reports will include
+only object addresses.
+<P>
+For more precise error reports, as much of the program as possible
+should use the all uppercase variants of these functions, after
+defining <TT>GC_DEBUG</tt>, and then including <TT>gc.h</tt>.
+In this environment <TT>GC_MALLOC</tt> is a macro which causes
+at least the file name and line number at the allocation point to
+be saved as part of the object.  Leak reports will then also include
+this information.
+<P>
+Many collector features (<I>e.g</i> stubborn objects, finalization,
+and disappearing links) are less useful in this context, and are not
+fully supported.  Their use will usually generate additional bogus
+leak reports, since the collector itself drops some associated objects.
+<P>
+The same is generally true of thread support.  However, as of 6.0alpha4,
+correct leak reports should be generated with linuxthreads.
+<P>
+On a few platforms (currently Solaris/SPARC, Irix, and, with -DSAVE_CALL_CHAIN,
+Linux/X86), <TT>GC_MALLOC</tt>
+also causes some more information about its call stack to be saved
+in the object.  Such information is reproduced in the error
+reports in very non-symbolic form, but it can be very useful with the
+aid of a debugger.
+<H2>An Example</h2>
+The following header file <TT>leak_detector.h</tt> is included in the
+"include" subdirectory of the distribution:
+<PRE>
+#define GC_DEBUG
+#include "gc.h"
+#define malloc(n) GC_MALLOC(n)
+#define calloc(m,n) GC_MALLOC((m)*(n))
+#define free(p) GC_FREE(p)
+#define realloc(p,n) GC_REALLOC((p),(n))
+#define CHECK_LEAKS() GC_gcollect()
+</pre>
+<P>
+Assume the collector has been built with -DFIND_LEAK.  (For very
+new versions of the collector, we could instead add the statement
+<TT>GC_find_leak = 1</tt> as the first statement in <TT>main</tt>.
+<P>
+The program to be tested for leaks can then look like:
+<PRE>
+#include "leak_detector.h"
+
+main() {
+    int *p[10];
+    int i;
+    /* GC_find_leak = 1; for new collector versions not 	*/
+    /* compiled with -DFIND_LEAK.				*/
+    for (i = 0; i < 10; ++i) {
+	p[i] = malloc(sizeof(int)+i);
+    }
+    for (i = 1; i < 10; ++i) {
+	free(p[i]);
+    }
+    for (i = 0; i < 9; ++i) {
+	p[i] = malloc(sizeof(int)+i);
+    }
+    CHECK_LEAKS();
+}	
+</pre>
+<P>
+On an Intel X86 Linux system this produces on the stderr stream:
+<PRE>
+Leaked composite object at 0x806dff0 (leak_test.c:8, sz=4)
+</pre>
+(On most unmentioned operating systems, the output is similar to this.
+If the collector had been built on Linux/X86 with -DSAVE_CALL_CHAIN,
+the output would be closer to the Solaris example. For this to work,
+the program should not be compiled with -fomit_frame_pointer.)
+<P>
+On Irix it reports
+<PRE>
+Leaked composite object at 0x10040fe0 (leak_test.c:8, sz=4)
+        Caller at allocation:
+                ##PC##= 0x10004910
+</pre>
+and on Solaris the error report is
+<PRE>
+Leaked composite object at 0xef621fc8 (leak_test.c:8, sz=4)
+        Call chain at allocation:
+                args: 4 (0x4), 200656 (0x30FD0)
+                ##PC##= 0x14ADC
+                args: 1 (0x1), -268436012 (0xEFFFFDD4)
+                ##PC##= 0x14A64
+</pre>
+In the latter two cases some additional information is given about
+how malloc was called when the leaked object was allocated.  For
+Solaris, the first line specifies the arguments to <TT>GC_debug_malloc</tt>
+(the actual allocation routine), The second the program counter inside
+main, the third the arguments to <TT>main</tt>, and finally the program
+counter inside the caller to main (i.e. in the C startup code).
+<P>
+In the Irix case, only the address inside the caller to main is given.
+<P>
+In many cases, a debugger is needed to interpret the additional information.
+On systems supporting the "adb" debugger, the <TT>callprocs</tt> script
+can be used to replace program counter values with symbolic names.
+As of version 6.1, the collector tries to generate symbolic names for
+call stacks if it knows how to do so on the platform.  This is true on
+Linux/X86, but not on most other platforms.
+<H2>Simplified leak detection under Linux</h2>
+Since version 6.1, it should be possible to run the collector in leak
+detection mode on a program a.out under Linux/X86 as follows:
+<OL>
+<LI> Ensure that a.out is a single-threaded executable.  This doesn't yet work
+for multithreaded programs.
+<LI> If possible, ensure that the addr2line program is installed in
+/usr/bin.  (It comes with RedHat Linux.)
+<LI> If possible, compile a.out with full debug information.
+This will improve the quality of the leak reports.  With this approach, it is
+no longer necessary to call GC_ routines explicitly, though that can also
+improve the quality of the leak reports.
+<LI> Build the collector and install it in directory <I>foo</i> as follows:
+<UL>
+<LI> configure --prefix=<I>foo</i> --enable-full-debug --enable-redirect-malloc
+--disable-threads
+<LI> make
+<LI> make install
+</ul>
+<LI> Set environment variables as follows:
+<UL>
+<LI> LD_PRELOAD=<I>foo</i>/lib/libgc.so
+<LI> GC_FIND_LEAK
+<LI> You may also want to set GC_PRINT_STATS (to confirm that the collector
+is running) and/or GC_LOOP_ON_ABORT (to facilitate debugging from another
+window if something goes wrong).
+</ul
+<LI> Simply run a.out as you normally would.  Note that if you run anything
+else (<I>e.g.</i> your editor) with those environment variables set,
+it will also be leak tested.  This may or may not be useful and/or
+embarrassing.  It can generate
+mountains of leak reports if the application wasn't designed to avoid leaks,
+<I>e.g.</i> because it's always short-lived.
+</ol>
+This has not yet been thropughly tested on large applications, but it's known
+to do the right thing on at least some small ones.
