Subject: Patch: symlinks for opendir()
Content-Type: text/plain; charset=iso-8859-4
Content-Transfer-Encoding: 7bit
Reply-To: djgpp-workers AT delorie DOT com

Adds symlink support to opendir() company.
However, only directory as passed to it is resolved.
Directory entries in readdir() are not resolved,
as glibc does.

Any comments?
Laurynas
