newlib/winsup/cygwin/winsup.h
Corinna Vinschen c4e6ff484c * fhandler.cc (fhandler_base::fstat): Initialise tv_nsec member of 
st_atim, st_mtim, and st_ctim fields.
	* fhandler_disk_file.cc (fhandler_disk_file::fstat_helper): Ditto.
	* fhandler_process.cc (fhandler_process::fstat): Ditto.
	* glob.c (stat32_to_STAT): Copy across the whole st_atim,
	st_mtime, and st_ctim fields.
	* syscalls.cc (stat64_to_stat32): Ditto.
	* times.cc (to_timestruc_t): New function.
	(time_as_timestruc_t): New function.
	* winsup.h: Add to_timestruc_t and time_as_timestruc_t functions.
	* include/cygwin/stat.h: Replace time_t with timestruc_t
	throughout for all file times, removing the st_spare1, st_spare2,
	and st_spare3 fields in the process. Add macros to access tv_sec
	fields by old names.
	* include/cygwin/types.h: Typedef timespec_t and timestruc_t as
	struct timespec.
