Re: DLL generation under Cygwin

[Larry Hall <cygwin-lh@cygwin.com>]

If your DLL was built against the Cygwin DLL, you'll have difficulties
because the Cygwin DLL won't be loaded properly.  Try building with 
'gcc -mno-cygwin'.  Of course, if you need the POSIX APIs Cygwin 
provides, you'll now have to do some porting.
