obstack: pacify HP C

* lib/obstack.h (obstack_free) [!__GNUC__]: Rewrite to avoid
warning "conversion from pointer to smaller integer" from HP
C-ANSI-C - cc version B9007AA/B3910B A.06.26.  It's safe to assume
C89 or later nowadays, so cast to void instead of int.  Privately
reported by H.Merijn Brand.  Also, change header to match glibc's,
to make checking against glibc easier.
