Folks, what is the current status of -ffast-math for gcc4 under cygwin. I tried to use it for some numerical C code and get the following link errors: eval.o:eval.c:(.text+0x79c): undefined reference to `_f_pow' eval.o:eval.c:(.text+0x7d8): undefined reference to `_f_log' eval.o:eval.c:(.text+0x7f0): undefined reference to `_f_exp' Was not able to find the library where theses thingies live! Thx., H. P.S. before I forget: $ gcc --version gcc (GCC) 4.3.4 20090804 (release) 1 $ uname -a CYGWIN_NT-5.1 HansHorn 1.7.0(0.217/5/3) 2009-11-03 15:06 i686 Cygwin -- 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
