[Bug-gnulib] obstack.h fix: obstack_base

[Jim Meyering]

FYI, I've just checked in the change below.
Before, obstack_base simply inherited the type of
the object_base member, `char *'.
So, be warned that if your code relied on the old,
incompatible-with-documented, behavior, it may no longer compile.

        * obstack.h (obstack_base): Cast to (void *), per documentation.
