[ChangeLog]

Assume S_ISLNK etc. work, since gnulib supports this.
* Makefile.in (GNULIB_MODULES): Add sys_stat.
* configure.in: Check for lstat and set HAVE_LSTAT=0 if not.
Pretend to be using the gnulib lstat module for benefit of sys/stat.h.
* configure, lib/Makefile.in, lib/gnulib.mk: Regenerate.
[lib-src/ChangeLog]
Assume S_ISLNK etc. work, since gnulib supports this.
* etags.c (S_ISREG): Remove.
[src/ChangeLog]
Assume S_ISLNK etc. work, since gnulib supports this.
* config.in: Regenerate.
* dired.c (lstat): Remove.
(file_name_completion): Assume S_ISDIR works.
(file_name_completion_stat): Assume S_ISLNK works.
Do not bother calling stat unless lstat says it's a symlink.
* fileio.c (S_ISLNK, S_ISFIFO, S_ISREG, lstat): Remove.
(Fcopy_file): Assume S_ISREG and S_ISLNK work.
(check_writable, Ffile_writable_p, Fset_file_times):
Assume S_ISDIR works.
(Ffile_readable_p): Use S_IFIFO, not S_ISFIFO, to guess whether
fifos exist.
(Ffile_regular_p, Finsert_file_contents): Assumes S_ISREG works.
* filelock.c (S_ISLNK): Remove.
* lread.c (openp): Assume S_ISDIR works.
* xrdb.c (S_ISDIR): Remove.
