[petsc-dev] extern "C" anachronism

"vecregall.c", line 43: Warning (Anachronism): Formal argument 4 of type
int(*)(_p_Vec*) in call to VecRegister(const char*, const char*, const
char*, int(*)(_p_Vec*)) is being passed extern "C" int(*)(_p_Vec*).

And lots of warnings like it.  Is it worth using an extern "C" typedef so
that the argument of XXXRegister is labeled extern "C", or is it not worth
it?
