(sdata): Implement in terms of struct sdata. Remove u member; all uses replaced by next_vector, set_next_vector. (SDATA_SELECTOR, SDATA_DATA, SDATA_DATA_OFFSET): Adjust to sdata change. (SDATA_DATA_OFFSET): Now a constant, not a macro. (struct sblock): Rename first_data member to data, which is now a flexible array member. All uses changed. (next_vector, set_next_vector, large_vector_vec): New functions. (vector_alignment): New constant. (roundup_size): Make it a multiple of ALIGNOF_STRUCT_LISP_VECTOR, too. (struct large-vector): Now merely a NEXT member, since the old approach ran afoul of stricter C99. All uses changed to use large_vector_vec or large_vector_offset. (large_vector_offset): New constant. * src/dispnew.c: Include tparam.h, for tgetent. Do not include term.h; no longer needed. * src/gnutls.c (Fgnutls_boot): Don't continue after calling a _Noreturn. * src/lisp.h (ENUM_BF) [__SUNPRO_C && __STDC__]: Use unsigned int. (struct Lisp_Vector): Use a flexible array member for contents, instead of a union with a member that is an array of size 1. All uses changed. (ALIGNOF_STRUCT_LISP_VECTOR): New constant, to make up for the fact that the struct no longer contains a union. (struct Lisp_Misc_Any, struct Lisp_Marker, struct Lisp_Overlay) (struct Lisp_Save_Value, struct Lisp_Free): Use unsigned, not int, for spacers, to avoid c99 warning. (union specbinding): Use unsigned, not bool, for bitfield, as bool is not portable to pre-C99 hosts.

In practice this is not a problem, but might as well do it by the book. Reported by Rich Felker and Eric Blake; see <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00493.html>. * m4/mktime.m4 (AC_FUNC_MKTIME): Likewise. * lib/mktime.c (TYPE_MAXIMUM): Redo slightly to match the others. mktime: #undef mktime before #defining it * lib/mktime.c (mktime) [DEBUG]: #undef mktime before #defining it. mktime: systematically normalize tm_isdst comparisons * lib/mktime.c (isdst_differ): New function. (__mktime_internal): Use it systematically for all isdst comparisons. This completes the fix for libc BZ #6723, and removes the need for normalizing tm_isdst. See <http://sourceware.org/bugzilla/show_bug.cgi?id=6723> (not_equal_tm) [DEBUG]: Use isdst_differ here, too. mktime: fix some integer overflow issues and sidestep the rest This was prompted by a bug report by Benjamin Lindner for MinGW <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00472.html>. His bug is due to signed integer overflow (0 - INT_MIN), and I I scanned through mktime.c looking for other integer overflow problems, fixing all the bugs I found. Although the C Standard says the resulting code is still not safe in the presence of integer overflow, in practice it should be good enough for all real-world two's-complement implementations, except for debugging environments that deliberately trap on integer overflow (e.g., gcc -ftrapv). * lib/mktime.c (WRAPV): New macro. (SHR): Also check that long_int and time_t shift right in the usual way, before using the fast-but-unportable method. (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer used. The code already assumed two's complement, so there's no need to test for alternatives. All uses removed. (TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by the C standard. Problem reported by Rich Felker in <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00488.html>. (twos_complement_arithmetic): Also check long_int and time_t. (time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions. (guess_time_tm, ranged_convert, __mktime_internal): Use them. (__mktime_internal): Avoid integer overflow with unary subtraction in two instances where -1 - X is an adequate replacement for -X, since the calculations are approximate. 2011-01-29 Eric Blake <eblake@redhat.com> mktime: avoid infinite loop * m4/mktime.m4 (AC_FUNC_MKTIME): Avoid overflow on possibly-signed type; behavior is still undefined but portable to all known targets. Reported by Rich Felker. 2011-01-28 Paul Eggert <eggert@cs.ucla.edu> mktime: avoid problems on NetBSD 5 / i386 * lib/mktime.c (long_int): New type. This works around a problem on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits but time_t is 64 bits, and where I expect the existing code is wrong in some cases. (leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it. (ydhms_diff): Bring back the compile-time check for wide-enough year and yday. mktime: fix misspelling in comment * lib/mktime.c (__mktime_internal): Fix misspelling in comment. This merges all recent glibc changes of importance. 2011-01-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> move-if-change: cope with concurrent mv of identical file. * move-if-change (CMPPROG): Accept environment variable as an override for `cmp'. (usage): Document CMPPROG. Adjust comparison to drop stdout. Cope with failure of mv if the target file exists and is identical to the source, for parallel builds. Report from H.J. Lu against binutils in PR binutils/12283.
