Repository description is lacking.

Is it a C compiler in 4 functions?

[whitten]

Well, a subset of C. (enough to compile itself)

[y12uc231]

Please improve the description.What exactly is this?

[vi]

Maybe the author wants the description to be exactly 4 words?

Suggested description:

Tiny (only 4 functions) interpreter of a subset of C for i386 architecture.

[pclouds]

To be pedantic, it's both a compiler and an interpreter. And it should run on other 32-bit platforms as well, at least ARM.

[feroldi]

void next();
void expr();
void stmt();
int main();

Yep. Four functions.

Could be

C4 - a subset-c compiler / interpreter structured in 4 functions targeted at 32-bit architectures

[jxu]

It compiles to custom bytecode which it also can interpret using a stack machine.
