Has the same vibes as anthropic creating a C compiler which passes 99% of compiler tests.

That last percent is really important. At least that last percent are some really specific edge cases right?

Description:
When compiling the following code with CCC using -std=c23:

bool is_even(int number) {
   return number % 2 == 0;
}

the compiler fails to compile due to bool, true, and false being unrecognized. The same code compiles correctly with GCC and Clang in C23 mode.

Well fuck.

If this wasn't 100% vibe coded, it would be pretty cool.

A c compiler written in rust, with a lot of basics supported, an automated test suite that compiles well known c projects. Sounds like a fun project or academic work.

any llm must have several C compilers in its training data, so it would be a reasonably competent almost-clone of gcc/clang/msvc anyway, right?

is what i would have said if you didn't put that last part
