#3I think Oberon would be a better candidate for this than C. You could get a tiny and extremely fast compiler for a full-featured programming language.

I'm looking into self-hosting compilers, is there a good link for Oberons code that achieves this? Or you just are mentioning that Oberon would probably be able to if one were implemented?

Oberon is implemented in itself: http://www.projectoberon.com
The implementation includes the hardware too.
Taken together, the system including single-tasking OS, windowing system and Oberon takes about 9000 lines of code.

#8In particular, the code for this compiler doesn't use structs. It only works with offsets to memory blocks.

at the bottom of the linked page the author explicitly references oberon as a source of inspiration for this project

#10The C subset it compiles is called C* but it appears unrelated to the language of the same name created for the Connection Machine hardware:
