A C compiler that fits within the 512 byte boot sector
SectorC (github) is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written.

That's quite an impressive achievement!
