Subject:	Patch: symlinks in mkstemp()
Reply-To:	djgpp-workers AT delorie DOT com

This is the last missing piece in symlink puzzle, as pointed
out by Eli. I'll submit yet another one patch which makes 
open() to resolve leading dirs even with O_NOLINK flag, but
is there anything else skipped?

Tested, works[*].

Any comments?

Laurynas

[*] For me.
