Apparently the man pages fpclassify exists and is C99. There where
times
when one could at least rely on what the man pages say...
fpclassify proved problematic (not available on windows anyway, has
_fpclass function) so removed to experimental file
"fpclassify.scm" (in svn but not egg)
The log2 & tgamma messages above indicate neither is available on
your platform. Chgd to not use 'log2' & use 'gamma' instead of
'tgamma' (which probably is available).
Try it now.
Sorry,
Kon
P.S. started down the path of autoconf but windows you know...
cheers,
felix
