OK, I'm moving the thread in the right mailing list... Something I forgot to mention is that I'm on XP Pro 64 bits, could that be of some influence? I tried to compile with x86_64-w64-mingw32-gcc, but then I get a lot of missing libraries... I'll more than appreciate any help! :-) BR, Max. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
