ARI just complains about it :-)

From the TODO file.

	Replace savestring() with something from libiberty.

	An xstrldup()? but that would have different semantics.

There may be more on this in the GDB and OpenBSD e-mail archives.  I
sent an e-mail to the OpenBSD group asking if there should be a
strldup() like function - the strl*() functions originated from someone
in OpenBSD land.

Anyway, yes, some instances of savestring should be xstrdup() but others
are not so should probably get ``X'' rated treatment :-)

As for size_t.  I have no idea, does libiberty manage to use size_t in
its headers?  If it does then, why not :-)
