See + <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00554.html>. + + 2011-01-29 Paul Eggert <[email protected]> + + TYPE_MAXIMUM: avoid theoretically undefined behavior + * lib/intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a + negative number, which the C Standard says has undefined behavior. + 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 <[email protected]> + + 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 <[email protected]> + + 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 <[email protected]> + + 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. + +2011-01-29 Eli Zaretskii <[email protected]> + + * lib/makefile.w32-in: + * lib/getopt_.h: New files. + +2011-01-28 Paul Eggert <[email protected]> + + improve fix for MS-DOS file name clash + * Makefile.in (DOS_gnulib_comp.m4): Renamed from DOS-gnulib-comp.m4, + for portability to POSIX make. Reported by Bruno Haible. + (sync-from-gnulib): Copy gl-comp.m4 (if present) back to + gnulib-comp.m4 before running gnulib-tool, to prevent old gnulib + files from accumulating as garbage. Also reported by Bruno Haible. + +2011-01-27 Paul Eggert <[email protected]> + + fix two m4/gnulib-*.m4 file names that clashed under MS-DOS + * Makefile.in (DOS-gnulib-comp.m4): New macro. + (sync-from-gnulib): Rename m4/gnulib-comp.m4 to m4/gl-comp.m4 to avoid + problems with MS-DOS 8+3 file name restrictions. + Remove m4/gnulib-cache.m4, as we can live without it. If we kept + it, it would also cause problems when extracting Emacs distribution + tarballs on MS-DOS hosts. + (ACLOCAL_INPUTS): Adjust to file renaming. + * aclocal.m4, configure, lib/Makefile.in, src/config.in: Regenerate. + * config.guess, config.sub: Sync from gnulib. + * m4/gnulib-cache.m4: Remove from repository. + * m4/gl-comp.m4: Rename from m4/gnulib-comp.m4. + +2011-01-25 Glenn Morris <[email protected]> + + * README: Add a note about ranges in copyright years. + + * configure.in: Set CANNOT_DUMP on ia64 hpux (port from emacs-23). + +2011-01-25 Peter O'Gorman <[email protected]> (tiny change) + + * configure.in: Add HP-UX on IA64 (Bug#6811). + +2011-01-24 Paul Eggert <[email protected]> + + Remove HAVE_RAW_DECL_CHOWN etc. from config.h + * Makefile.in (sync-from-gnulib): Remove m4/warn-on-use.m4, + as it is no longer needed. + * aclocal.m4, configure, lib/Makefile.in, src/config.in: Regenerate. + * configure.in: Invoke the new gnulib macro + gl_ASSERT_NO_GNULIB_POSIXCHECK, which removes the need for + warn-on-use.m4 and for the HAVE_RAW_DECL_* symbols in config.h. + * m4/getopt.m4: Sync from gnulib; this removes the need for + HAVE_DECL_OPTRESET and HAVE_DECL_GETOPT_CLIP from config.h. + * m4/gnulib-common.m4 (gl_ASSERT_NO_GNULIB_POSIXCHECK): + New macro, synced from gnulib. + * m4/warn-on-use.m4: Remove. + +2011-01-22 Paul Eggert <[email protected]> + + aclocal.m4: put this file back into repository + This way, we don't have to assume that the maintainer has + the automake package installed.

This removes a few more unnecessary symbols from + src/config.in, such as AA_APPLE_UNIVERSAL_BUILD and HAVE_STDDEF_H. + * configure, src/config.in: Regenerate. + + aclocal.m4: tweaks to regenerate more conveniently + This attempts to act better when the source is in a weird state. See + <http://lists.gnu.org/archive/html/emacs-devel/2011-01/msg00734.html>. + * Makefile.in (am--refresh): Add aclocal.m4, configure, config.in. + * .bzrignore: Add aclocal.m4. + +2011-01-20 Paul Eggert <[email protected]> + + aclocal.m4: omit auto-generated file from repository + * Makefile.in (top_maintainer_clean): Remove aclocal.m4; this undoes + the most recent change here. + * aclocal.m4: Remove from bzr repository.

IBM AIX and Oracle Solaris Studio support + this syntax. + +2011-01-17 Paul Eggert <[email protected]> + + Makefile.in: tidy up the building of lib + * Makefile.in (am--refresh): Mark as .PHONY. + (top_maintainer_clean): Don't remove lib/gnulib.mk m4/gnulib-cache.m4, + as they're not rebuilt unless you do a "make sync-from-gnulib" + and the former is needed for "configure". + (maintainer-clean): Don't recurse into lib, as "make bootstrap-clean" + has already removed lib/Makefile. + + * Makefile.in (GNULIB_MODULES): Change ftoastr to dtoastr. + This avoids building ftoastr and ldtoastr, which aren't needed. See + <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00199.html>. + + * .bzrignore: Add .h files that are host-dependent. + Add lib/.deps/, lib/arg-nonnull.h, lib/c++defs.h, lib/getopt.h, + lib/time.h, lib/unistd.h, lib/warn-on-use.h.
