utimensat: work around Solaris 9 bug utimes("file/",times) mistakenly succeeds. This commit doesn't fix utimes, but does make utimensat be careful before calling utimes. The test is now enhanced to test trailing slashes and directories. Meanwhile, cygwin 1.5 stat() on a directory changes atime (it does a readdir under the hood to populate st_nlink), so only mtime of a directory is reliable enough for testing. Cygwin 1.7 no longer has this problem, because it no longer wastes time on st_nlink. * lib/utimens.c (fdutimens, lutimens): Force a stat if platform has trailing slash bugs. * tests/test-lutimens.h (test_lutimens): Enhance test. * tests/test-utimens.h (test_utimens): Likewise. * doc/posix-functions/utime.texi (utime): Document the bug. * doc/posix-functions/utimes.texi (utimes): Likewise. * doc/posix-functions/utimensat.texi (utimensat): Likewise. * doc/glibc-functions/futimesat.texi (futimesat): Likewise. * doc/glibc-functions/lutimes.texi (lutimes): Mention utimens. * doc/posix-functions/futimens.texi (futimens): Mention limitation.
