I took Ron Cain's Small-c, which is written in a subset of K&R C, and
put a nasm backend to it. Small-c is a bootstrap K&R C, a minimalist
K&R C compiler written in its minimalist K&R C. It is a complete
enough K&R C to self compile, without for(;;) and switch(expr) and
struct{}. In other words, the parser parses a subset of K&R C, not
the complete grammar of the appendix. Later on, others expanded
Cain's Small-c to add much of the remaining grammar, and ports to
other OS's.


Anyway, my Small-c project is here:

I targeted the iolib to use XP's cmd.exe for my convenience.


I recommend you copy all of the site that you want for future
reference, I don't know how long it will be maintained.
