One of our offices is trying to prepare some binaries for us. They are
running on a 3B2/500, but we are using a 400.
Unfortunately, any binaries they send us won't run because they
require an MAU. Is there any way to force cc to use software emulation of
the MAU so that the binaries can be used on anything from a 310 upwards?

The gencc(1) command can be used to generate a new front end for
the cc(1) command, and one of the options is treatment of floating point.
So, you could have them use a new front end or just use the command
/lib/cc -K fpe "$@" to compile the programs that will be run on the
400. Note that I am assuming that you have CPLU 4.2. The default
/bin/cc on a [567]00 contains /lib/cc -K mau "$@" so it's no surprise
that you're having problems running the products of such compilations
on a 400.
For this to work, the person that installed CPLU on the 500 must have
specified "both" when asked whether to load mau or fpe upon installation.
Good Luck,
Gregg Siegfried

In Gregg's otherwise superb reply he mentioned:

Whoa! The 310 and 400 are pretty likely to have mau's.. I don't see why
it would be likely that one would have problems using hardware floating
point software on a 400.
