-== gc_cpp.h usage ==
-
-Replacement of operator new and delete is apparently not supported with
-dynamic libraries.  This means that applications using gc_cpp.h
-(including the built-in test) will probably not work correctly with
-the collector in a dynamic library, unless special care is taken.
-
-See

-While the GC should work on MacOS X Server, MacOS X and Darwin, I only tested
-it on MacOS X Server.
-I've added a PPC assembly version of GC_push_regs(), thus the setjmp() hack is
-no longer necessary. Incremental collection is supported via mprotect/signal.
-The current solution isn't really optimal because the signal handler must decode
-the faulting PPC machine instruction in order to find the correct heap address.
-Further, it must poke around in the register state which the kernel saved away
-in some obscure register state structure before it calls the signal handler -
-needless to say the layout of this structure is no where documented.
-Threads and dynamic libraries are not yet supported (adding dynamic library
-support via the low-level dyld API shouldn't be that hard).
-
-The original MacOS X port was brought to you by Andrew Stone.

-Note from Andrew Begel:
-
-One more fix to enable gc.a to link successfully into a shared library for
-MacOS X. You have to add -fno-common to the CFLAGS in the Makefile. MacOSX
-disallows common symbols in anything that eventually finds its way into a
-shared library. (I don't completely understand why, but -fno-common seems to
-work and doesn't mess up the garbage collector's functionality).

-Jeff Sturm and Jesse Rosenstock provided a patch that adds thread support.
-GC_THREADS should be defined in the build and in clients.  Real
-dynamic library support is still missing, i.e. dynamic library data segments
-are still not scanned.  Code that stores pointers to the garbage collected
-heap in statically allocated variables should not reside in a dynamic
-library.  This still doesn't appear to be 100% reliable.

-Brian Alliet contributed dynamic library support for MacOSX.  It could also
-use more testing.
