/* XXX */
/*
* This file was derived from source obtained from NetBSD/Alpha which
* is publicly available for ftp. The patch was developed by cgd@netbsd.org
* during the time he worked at CMU. He claims that CMU own this patch
* to gcc and that they have not (and will not) release the patch for
* incorporation in FSF sources. We are supposedly able to use the patch,
* but we are not allowed to forward it back to FSF for inclusion in
* their source releases.
*
* This all has me (jb@freebsd.org) confused because (a) I see no copyright
* messages that tell me that use is restricted; and (b) I expected that
* the patch was originally developed from other files which are subject
* to GPL.
*
* Use of this file is restricted until its CMU ownership is tested.
