Subject: Modula-2 and other languages (under UNIX on VAX)

Does anyone know of any Modula-2 compilers that let you call modules or
functions written in other languages?

What I need is a way to do things in a Modula-2 program that I can't do
in Modula-2, i.e.  generate certain priviledged VAX instructions (this
is for the innermost layers of an operating system we are writing).  We
currently do this (in a Modula [NOT Modula-2] PDP-11 compiler) with
"code escapes" which allow one to embed assembly language directly in
the source.

Also, I was wondering if there is a general-purpose mechanism for
linking j.  random object modules with Modula-2 objects, so I could use
"C" for some functions, or better yet, write a Modula-2 library module
which could be linked with a "C" program, so I only have to maintain 1
run-time system.

Thanks,
