Perhaps I should run servers build by gcc -mno-cygwin more often. I
usally cross compile the stuff. And when I compile with normal gcc
-mno-cygwin, I usually only run the client. And the server compiles
always happily.  
That's evil.

You can fix the problem if you don't link against -lm. -lm seems to
conflict with wsock32.dll (It adds cygwin1.dll!) on recent versions of
cygwin. It has worked with earlier versions.
