I've heard of that; it used to be called LoseThos. The guy who wrote it is schizophrenic and occasionally replaces his entire website and fills his twitter with delusional rants.
The "C compiler" is actually a compiler for a language he invented called C+. I assume it's some kind of cross between C and C++. I feel bad for him, he's been ostracised from every OS development community he's tried to join (or at least, all the ones I'm aware of). His OS looks horrible, but you have to respect the amount of effort and ingenuity he poured into writing it.
