[PATCH] Avoid floatformat_from_doublest() assertion failure

[Kevin Buettner <kevinb@redhat.com>]

I've just committed the change below.

On Irix, I was running into an assertion failure in
floatformat_from_doublest() due to fmt being NULL.  (gdb can't handle
16 byte long doubles.)  The caller was store_floating() and, prior to
the call, had determined that fmt was NULL and had printed a suitable
warning.  Moreover, the return value had been filled in with a
suitable value.  (Well, as suitable as possible for something that
gdb says it can't do.)

	* doublest.c (store_floating): Avoid floatformat_from_doublest()
	assertion failure by returning early after a warning.
