Yes, this seems to help. At least building gcc-2.95 for sh-rtems doesn't fail
anymore when replacing the SH's backend (gcc/config/sh) with the version on CVS
from the main-line branch.

Perhaps one should consider to merge the sh-backend of the main-line branch into
gcc-2.95 therefore - However I did not run any program on actual hardware yet :-.
