Don't use lvalue casts, as GCC plans to remove support for
them
in GCC 3.5. Reported by Joseph S. Myers. This bug
was also present in the non-GCC version, indicating that this
code had always been buggy and had never been widely used.
(obstack_1grow, obstack_ptr_grow, obstack_int_grow,
obstack_blank):
Use the fast variant of each macro, rather than copying the
definiens of the fast variant; that way, we'll be more likely
to
catch future bugs in the fast variants.
