* year2038: support glibc 2.34 _TIME_BITS=64Paul Eggert2021-07-011-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | In glibc 2.34 on Linux kernels where time_t is traditionally 32-bit, defining _FILE_OFFSET_BITS=64 and _TIME_BITS=64 makes time_t 64-bit. Apps must define both macros. Gnulib applications that use either the largefile or the year2038 modules will want this behavior; largefile because it deals with the off_t and ino_t components of struct stat already, and so should also deal with time_t. * NEWS, doc/largefile.texi, doc/posix-headers/time.texi: Mention this. * m4/largefile.m4: Override two macros even in Autoconf 2.70 and later. (_AC_SYS_LARGEFILE_MACRO_VALUE): #undef $1 before #defining it, in case some other Gnulib macro has #defined it. (AC_SYS_LARGEFILE): Use AS_IF and AS_CASE to propagate AC_REQUIREs. Invoke gl_YEAR2038_BODY if we need to set _FILE_OFFSET_BITS=64. * m4/year2038.m4 (gl_YEAR2038_TEST_INCLUDES): New macro. (gl_YEAR2038_BODY): New macro, with gl_YEAR2038’s old body; this macro is designed to be used directly instead of being AC_REQUIREd. It takes an argument specifying whether 64-bit is required. Set _TIME_BITS=64 if this makes a difference in time_t width when setting _FILE_OFFSET_BITS=64. Do not warn about 32-bit time_t more than once. * modules/largefile (Files): Add year2038.m4. (Depends-on): Require gl_YEAR2038_EARLY.

| | | | | | | | | | With no configure.ac-early, and two configure.ac sections, gnulib-tool only picked up the second (empty) section, and thus completely skipped any AC_SYS_LARGEFILE call altogether. * modules/largefile (configure.ac-early): Fix section name.
