The #define of powf() doesn't work on UNIX systems that don't support powf() in -lm, like Solaris 2.6 and 7. So, I modified autoconf to detect powf and modified #ifdef _MSC_VER to substitute the #define powf on systems that don't support it. Patch attached. -- albert chin (china@xxxxxxxxxxxxxxxxxx)
