ISO C prototype style for libiberty?

"Should be" does not mean "is".  I know libiberty has been used for
this purpose in the past (remember the demangler in libstdc++ times?)
so I wouldn't want to assume we aren't still doing it.

That's hard for libiberty, where it is also used for target systems.
