9.491 lchown

POSIX specification:
http://www.opengroup.org/onlinepubs/9699919799/functions/lchown.html

Gnulib module: lchown

Portability problems fixed by Gnulib:

• Some platforms fail to detect trailing slash on non-directories, as in lchown("link-to-file/",uid,gid): FreeBSD 7.2, Solaris 9.
• Some platforms fail to update the change time when at least one argument was not -1, but no ownership changes resulted. However, without lchmod, the replacement only fixes this for non-symlinks: OpenBSD 4.0.
• This function is missing on some platforms; however, the replacement fails on symlinks if chown is supported, and fails altogether with ENOSYS otherwise: Mac OS X 10.3, Minix 3.1.8, mingw, MSVC 9, BeOS.
