http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00210.html
has a really old example.  I'd expect other really old compilers to also
have this limitation, but could not name one which is in common use.

Surely they would be, but only when libtool is not in use.  It still
does its own per-language `-c -o' testing, and may always be called
with both arguments.
