Yep!  That worked! Well mostly... 'guile-config link' doesn't return
the correct string (-L/usr/local/lib is AFTER -lguile) but that's
easily fixed with a little shell script magic.

I'll see if I can ping the maintainer.

I'm still having problems with the lastest version.  I've been told
that it was due to the Cygwin Guile using a different version of gcc
then what is shipped with Cygwin.   No idea if that's true.

Yep, that's what I've been told.  Limited testing so far seems to
indicate this does fix the problem (autogen isn't crashing anymore,
except for using it with pipes: 'autogen -v | echo' for example).

Thanks!
