* doc/posix-functions/stat.texi: Mention the problem with the Microsoft
implementations of stat().
* lib/stat.c: Include filename.h instead of dosname.h. Include
malloca.h, stat-w32.h.
(is_unc_root): New function.
(rpl_stat): New implementation for native Windows. Remove
REPLACE_FUNC_STAT_DIR code.
* m4/stat.m4 (gl_FUNC_STAT): On native Windows, set REPLACE_STAT always.
Don't define REPLACE_FUNC_STAT_DIR.
(gl_PREREQ_STAT): Require gl_HEADER_SYS_STAT_H.
* modules/stat (Files): Add lib/stat-w32.h, lib/stat-w32.c.
(Depends-on): Remove dosname. Add filename, malloca.
(configure.ac): Also compile lib/stat-w32.c.
Like Solaris 9, FreeBSD 7.2 mistakenly allows stat("link-to-file/").
Unlike Solaris, it correctly forbids stat("file/"). A number of
interfaces are affected (such as utimes), but replacing stat is
enough to catch several by reusing the Solaris 9 fixes.
* m4/stat.m4 (gl_FUNC_STAT): Also detect FreeBSD bug with slash on
symlink.
* doc/posix-functions/stat.texi (stat): Document the bug.
* tests/test-stat.h (test_stat_func): Add argument.
* tests/test-stat.c (main): Adjust caller.
* tests/test-fstatat.c (main): Likewise.
* modules/stat-tests (Depends-on): Add stdbool, symlink.

* lib/sys_stat.in.h (stat): Declare replacement.
* lib/openat.c (fstatat): Deal with lstat and stat being function
macros.
