isnormal() and a load of other things are guarded by '#if !defined(__STRICT_ANSI__)' in math.h, and __STRICT_ANSI__ does get defined for -std=c99. It's definitely in the C99 standard though, so either the header is wrong or __STRICT_ANSI__ shouldn't be defined. -- 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/
