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.

P.S. started down the path of autoconf but windows you know...
