The CLR model has always had support for instruction to support the C/C++ language, compile plugins or similar once and load/run on multiple platforms should be possible.
However, iirc there might've been some issues with libraries making the cl /clr code unportable (don't quote me on that though), starting from scratch might yield a better result if one just wants to run C code everywhere.

One problem with lcc has always been that it's distributed as source available with restrictions and has never been available under a FOSS license.
