3.4 is not enough. You still need library support for most of the math functions. I got working float and double functions from Stephen Moshier's code http://www.moshier.net in a few hours coding last night. Seems to work with gcc CVS - accurate to one or two bits. Need some polishing though. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
