Subject: LD patches: i386-msdos and i386-moss targets
Date: Fri, 02 Jun 1995 10:14:00 -0000
Message-id: <199506021722.LAA10839@schirf.cs.utah.edu>
X-SW-Source: 1995/msg00093.html

(As requested, I'm submitting separate patches for the different
parts of the gas/binutils collection.
What's the appropriat list for GNU ld patches?)

Here are some very simple patches to GNU ld-950602.
They add a new target `i386-msdos', to go along with the
corresponding target already in bfd and gas.
They also add a new target `i386-moss', which is a DOS extender
I'll be releasing shortly (I'd like to have support for it in
the main binutils distribution by the time I release it).

Thanks!

				Bryan
