I worked at a company ("Morada Corp") in the early 90s that did just that for ... RPG II!
We took the code from IBM minicomputers and compiled it into C on many, many platforms (back when there were a few more unices, as well as OS/2 and VAX/VMS kicking around).
I only did a little maintenance on the compiler front end checker, though. I mostly worked on some supplemental tokenizers/runtimes for data file browser language and a DB/form DDL.
Anyway, GCC made a nice target to hit a large number of systems. (alas, Borland C on DOS at the time tended to choke on larger generated subroutines, being 16 bit w/out "huge" pointer support and all)
