lstat
POSIX specification:
http://www.opengroup.org/onlinepubs/9699919799/functions/lstat.html
Gnulib module: lstat
Portability problems fixed by Gnulib:
off_t is a 32-bit type, lstat may not
correctly report the size of files or block devices larger than 2 GB.
(Cf. AC_SYS_LARGEFILE.)
lstat("file/",buf) succeeds instead of
failing with ENOTDIR.
Solaris 9.
lstat does not exist.
Portability problems not fixed by Gnulib:
struct stat.
