Changes for Alpha and EGCS.
* Commonalities with i386, moved to a FreeBSD wide config file. * Major additions to this file were adapted from Hidetoshi Shimokawa <simokawa@FreeBSD.ORG>'s Alpha suppliment to the Egcs 1.1.2 port.

/*
|
||||
* 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.
