You say it needs only libc, but of course it needs
more than the ISO C library functions. Is the code written in a way
that makes it easy to port to other systems?
CRPC has two main parts - C-wrapper compiler and shared library.
Compiler is implicitly written with libc functions and standart Unix
system calls.
At this point it can be ported to any platform, that supports C.
Wrapper compiler is built on my own parser, it does not need Lex/Bison.
Parser partially implemets C syntax - variable declarations, typedefs and
function prototype declarations.
Library is dependent only on libc whether there is no need in threading support.
The system should work on any BSD-like system, I have tested on
Darwin(Power-PC),
and it was ok. Also system will work on 32-bit and 64-bit systems
(tested on amd64).
On Linux everything is ok. Port it on CygWin is not a big problem to.
I think this would have been useful on at least one project
in my history. :)
Ian mentioned embedded systems in an earlier question
and I am still unsure what you require of the OS in terms
of services to work. Cygwin is very close to a "real UNIX"
from a programming viewpoint.

RTEMS is a single process, multithreaded RTOS with
a port of the FreeBSD TCP/IP stack. Do you think that
would that be sufficient to run on?
Have you build this cross yet?
