* configure.ac (AC_CHECK_MEMBERS): Add stat.st_atim.tv_nsec, stat.st_ctim.tv_nsec, stat.st_mtim.tv_nsec, stat.st_atime_nsec, stat.st_atime_csec, and stat.st_mtime_nsec. * file.c: Explicitly define HAVE_STRUCT_STAT_ST_ATIME_NSEC, HAVE_STRUCT_STAT_ST_CTIME_NSEC and HAVE_STRUCT_STAT_ST_MTIME_NSEC for locally defined types. * printstat.h (DO_PRINTSTAT): Print st_atime_nsec, st_ctime_nsec, and st_mtime_nsec members. * tests/stat.c [_FILE_OFFSET_BITS == 64]: Use st_atime_nsec, st_ctime_nsec, and st_mtime_nsec via st_atim.tv_nsec, st_ctim.tv_nsec, and st_mtim.tv_nsec. (main): Print st_atime_nsec, st_ctime_nsec, and st_mtime_nsec members. This fixes Fedora bug #1251176.
