To fit the tokenizer in 512 bytes, the author develops Barely C, a C-like language with mega-tokens and using atoi() as a hash-like tokenizer. The first Barely C fits in 468 bytes with a simple recursive-descent parser and no symbol table; variables are addressed by a 16-bit hash; codegen uses ax and cx....
