I had reasonable success with a very simple macro-oriented approach.
M4 wasn't quite what I wanted, so I whipped up a preprocessor in Icon
(http://www.cs.arizona.edu/icon) to do the job. This worked fine
until the day we decided we didn't want just to emit C, we also wanted
to be able to emit Modula-3, or Java, or ML, or ... From that point
forward, code has gotten very klunky. The main problem seems to be
finding a reasonable internal representation of `program' that can be
mapped to any one of a number of programming languages. It's hard for
us to decide what features we want to exploit: objects? mutable state?
closures? memory management?


I'd love to hear from others who are successfully using multiple
high-level languages as target languages for a compiler or stub
generator.
