Normally, if you care, you would set something like -march=pentium-m, and, if you wish, -mfpmath=sse . All the usual data types are present (float, double, long double) and the storage is little-endian, same as any other compiler for the same CPU. -- 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
