Ah, I was not aware that the Debian package included a patch to modify
`fpu.c' and the line numbers Michael posted matched closely to an
invocation of `fp_save' which would in turn resort to `fnsave'.  This is
where I got that from.

Why isn't that patch in upsteam cvs?  Does it need more testing (as this
bug report might indicate)?

Also without the ``0 -> 16'' alignment patch?
