Hello bug-guile.

The problem below still seems to be present in a recent CVS checkout.
It seems that the environment variables that I have set are causing
'configure' to fail once it enters libltdl. Apparently the manner in
which they're being passed causes configure to interpret them as a
host specification.

I don't think you need to explicitly pass the variables at all. Simply
exporting the variables should be sufficient in making them available
to the sub-configure scripts.

(FWIW, this is the standard way that I build autoconf-based packages,
and this is the only time ever seen this error.)
