Fix warnings and errors building libiberty with pcc on vax-dec-ultrix4.3

It doesn't cause a problem with respect to compilation with either the vax
pcc or hpux traditional compilers.  However, I am not sure functionality
is tested.  dwarf2out.c appears to use the md5 module.  However,
we don't generate dwarf2 debug output on either vax ultrix or the
32-bit hpux port.  Possibly, this could be a problem on the 64-bit
hpux port.
