Re: [Tinycc-devel] Do you know of any forks of TinyCC?

[Michael B. Smith]

His commits remind me quite strongly of how I implemented C for Burroughs Corp. 
mainframes in the 1980s.

I started with a very minimal compiler written in Extended ALGOL, then made it 
self-hosting in C, then extended it, step-by-step, until it was a full compiler.

I took a different tack than FB did ... but different strokes, different folks.

Fun stuff.
