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
