glibc support for 64-bit time_t on 32-bit architectures will involve: - Using 64-bit times inside glibc, with conversions to and from 32-bit times taking place as necessary for interfaces using such times. - Adding 64-bit-time support in the glibc public API. This support should be dynamic, i.e. glibc should provide both 32-bit and 64-bit implementations and let user code choose at compile time whether to use the 32-bit or 64-bit interfaces. This requires a glibc-internal name for a type for times that are always 64-bit. Based on __TIMESIZE, a new macro is defined, __TIME64_T_TYPE, which is always the right __*_T_TYPE to hold a 64-bit-time. __TIME64_T_TYPE equals __TIME_T_TYPE if __TIMESIZE equals 64 and equals __SQUAD_T_TYPE otherwise. __time64_t can then replace uses of internal_time_t. This patch was tested by running 'make check' on branch master then applying this patch and its predecessor and running 'make check' again, and checking that both 'make check' yield identical results. This was done on x86_64-linux-gnu and i686-linux-gnu. * bits/time64.h: New file. * include/time.h: Replace internal_time_t with __time64_t. * posix/bits/types (__time64_t): Add. * stdlib/Makefile: Add bits/time64.h to includes. * time/tzfile.c: Replace internal_time_t with __time64_t.
