As Hrvoje has said, there have been some significant changes since
that date, so you might have more luck with latest CVS.

That's frustrating.  Surely this is a libtool-determined detail, so is
the problem that we're not using the right libtool, or do libtool
builds fail for all free software tarballs when building with the HP C
compiler?

I think we should just remove environments.c from the build, as it
isn't even used yet, and only causes us problems.  I've just done this
in CVS HEAD, and will do so in the branches also if no one objects.

I just don't think this is worth worrying about, until we decide
_really_ to plumb environments.[ch] into the rest of libguile.

This is the problem that has since been fixed in CVS.
