rtems patch for egcs-970901

To: egcs at cygnus dot com
Subject: rtems patch for egcs-970901
From: Joel Sherrill <joel at OARcorp dot com>
Date: Wed, 3 Sep 1997 09:36:17 -0500 (CDT)


This patch removes the SUBTARGET_SWITCHES for -mrtems.  When using user
defined specs files, the proper way to do it (thanks Michael Meissner) is
to use -qNAME.  This will not cause cc1 to complain and lets the user
extend the specs file.  Each RTEMS board support package includes a specs
extensions file to specify linker options, special libraries, etc.  This
patch makes the invocation correct based upon the current way -specs
works.

          definitions.  Use -qrtems instead of -mrtems.
