Thanks for the hand holding. I think I've nailed
the problem by running 'gcc -v'

It seemed to have been linking in an older version
of cygwin crt0.o, which was causing the trouble.

Thanks again!

OK, so you did provide the "simple program" in your first post.  I 
glossed over that.  However, it's not too much help since

int main(){return(0);}

compiles fine here.  Of course, I don't have the include file so I omitted
it from my test.  I'm guessing that's the source of your trouble.  Clearly, 
your attempt thinks it needs pthreads, though it's not clear why.  The rest 
of my original response still applies.  There really isn't any information 
that you've given that's helpful in tracking down your problem so you need 
to investigate a little more and report back with the specifics mentioned 
if you don't see the solution.
