Concurrent C is a different language. I can't take a couple of pages
of code and use them to implement threads for a C compiler and library
I don't have the source to. In many C compilers I wouldn't even need
to write any assembly code, since setjmp/longjmp can be used to implement
the context switch.

This is not nearly as ambitious a project as Concurrent C.
