sys_time: Override 'struct timeval' on some native Windows platforms. * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Test whether tv_sec has the right type. Set REPLACE_STRUCT_TIMEVAL if not. (gl_HEADER_SYS_TIME_H_DEFAULTS): Initialize REPLACE_STRUCT_TIMEVAL. * lib/sys_time.in.h: Include <winsock2.h> also when 'struct timeval' needs to be overridden. (timeval): Override if REPLACE_STRUCT_TIMEVAL is set. * modules/sys_time (Makefile.am): Substitute REPLACE_STRUCT_TIMEVAL. * tests/test-sys_select.c: Check that the tv_sec member has the same size as a 'time_t'. * tests/test-sys_time.c: Likewise. * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): If REPLACE_STRUCT_TIMEVAL is set, set also REPLACE_GETTIMEOFDAY. * lib/gettimeofday.c (gettimeofday): If 'struct timeval' is overridden, convert the resulting 'struct timeval' before returning. * lib/select.c: Include <sys/time.h>. (select, timeval): Undefine at the right place. * modules/select (Depends-on): Add sys_time. * doc/posix-headers/sys_time.texi: Mention the problem with tv_sec on some Windows platforms.
