gettimeofday: port recent C++ fix to Emacs Without this further patch, Emacs won't build due to the portcheck failing. Also, this simplifies the patch a bit. * lib/time.in.h (localtime, gmtime): Don't replace unless GNULIB_GETTIMEOFDAY. Treat them more like mktime. * lib/time.in.h (localtime, gmtime): * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): * modules/time (time.h): Don't worry about about the possibility of localtime and gmtime being absent; they're present in all C libraries we know about. * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): Don't assume sys_time is present and has been initialized. Instead, use a hack that should work even if it hasn't been. Don't use a portcheck for gmtime or localtime; this supports the hack. * modules/time (time.h): Substitute GNULIB_GETTIMEOFDAY.
