Does anyone have any information on a version of GNU C for
the transputer.  Does GNU C work on stack based machines?

Interesting question. I found the following in the GCC documentation :

				[gcc.info: ``GNU CC and Portability'']

The `several general registers' seem to be a problem. The
transputer does not have them.

An idea is to use the fast built-in memory of the transputer like
registers (with a accesstime between 1 cycle and 5 (?) cycles).
(Nice idea: It will be possible to get the address of a register variable :-)
But this results in a compiler for a (virtual) processor based on
the transputer-processor.

But i don't know if anyone is working on a port, or if a port is
possible ...
