OK, I installed a modified version of this patch.  My changes do not
assume a particular Fortran name mangling scheme, but instead use the
one found by configure.  Doing that complicated things a bit.  Since
it is fast and should no cause any harm on systems that don't need it,
I decided to always generate the cruft.defs file.  If this causes
trouble, then maybe we can arrange to disable it on the systems that
are affected.
