Subject: Patch: chown() preparation for symlinks
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Reply-To: djgpp-workers AT delorie DOT com

This patch changes !__file_exists(...) to access(..., F_OK).
access() will be converted to accept symlinks, and __file_exists()
won't be. chown() works with this change with and without symlinks.

Also it fixes warning about unused variables and removes redudant
includes.

OK to commit?
