I just noticed that in x_arithmetic.c, powf() and its single precision
friends are all macroed to the double precision version saying "MSW and
OSX don't appear to have single-precision ANSI math". But according to
/usr/include/architecture/ppc/math.h, it does have all them, you just
have to link in libmx:
/*
* N.B. When using the C99 "float" entry points that follow, an
additional
* flag must be added to the link step that produces the executable
binary
* -- specify "-lmx".
*/
Any problem with using the right functions on Mac OS X? This should
speed things up a bit, no? I'll make the patch if there's no
problem...
