There is a commercial C compiler available for MPE/V, and another that
could be freeware if we can solve a couple of legal problems. Unfortunately,
GCC/G++ won't compile for MPE V without a LOT of work. MPE/V is very much
a 16-bit architecture, and GCC/G++ assume the availability of more than
32k of data. It would be possible to change them, but I don't know that
you'll find anyone willing to do it.

C/iX is a good, solid compiler, and it knows about a lot of 3000-isms
that GCC/G++ don't, and probably won't for a while. The biggest
problem is the lack of the Modcal calling sequence for variable-length
and omitted parameters in parameter lists.
