If that's all you're looking for, why not look into other open source
C compilers.

If you want a quick and dirty subset of C that has good embedded support
the Small C compiler is pretty good.
Admittedly, it's a C subset, but it's extremely well documented

Alternately, there's EiC:
It's described as "The embeddable/extensible interactive, pointer-safe,
bytecode C interpreter/compiler."

I know, it's an interpreter, *however*, it may be possible to change the
bytecode so that it matches the CLR's. If that's possible, you'd get a
compiler and the framework for an interpreter for free. No work would be 
lost if a GCC implementation were made later.

One more alternative, if you're not concerned about managed extensions,
you could also look at a translator of GCC assembly language for a
simple CPU architecture (e.g. 8086) to CIL. Or take the approach used

I'm not sure if any of these are what you're looking for, but please
take a peek before doing any serious work.

Take care,
