Re: Simple source translation tool?

["Andy Glew" <glew@xxxxxxxxxxx>]

I frequently have need of such tools.
In the past I have hacked GCC and indent.
The problem with such hacks, of course, is that
they grow stale as the language evolves
(indent, for example, was based on pcc,
but drifted over time, and last I looked no longer
handled the full language).

The most recent tool I have used in this regard 
is OpenC++.
