It isn't set at all.

Is there a way that I can compile the stuff myself?   I still don't see what I need to
to do so.   Plain gcc package won't do I suppose.

And how does mingw as it comes with the net release relate to what is
on www.mingw.org?  Are these separate projects?  I really find this
confusing.

What I really like to do is build executables *under cygwin* that run without
cygwin1.dll.  I am not really interested in having a gcc (executable) that works
without cygwin1.dll.


Thanks for any insight,
Michael
