It looks like you fished the awk file out - I found http://cowlark.com/mercat/com.awk.txt linked directly on that page, which, at 1610 total lines (1518 SLOC counting commented-out code), sounds like exactly what you're referring to.

As for fforth.... your signoff at the end of the comments sums it up much better than anything I could say.

  # No evil was harmed in the making of this file. Probably.

This thing is absolutely awesome... a self-modifying tri-language source file, implementing Forth in just 22KB (or 34KB on x64). Very nice.

Now to go read the, um,

  panic: unrecognised word: help

...documentation? :P

It actually happens that I've recently become really interested in Forth implementations and systems, so discovering this is especially cool... and on that note, what sources would you recommend I study to get an overview of Forth history and development? I've read enough historical anecdotes to understand there are conflicting opinions (as always), but nothing thus far has shown the evolution of the language itself, how ANS became a thing, and so forth.

PS. clang-3.7 -Os is the winner on i386, gcc-5.3 -Os on x64. tcc-0.9.26, interestingly, comes second on both (26KB and 36KB respectively). (Using Slackware-current.)

PPS. Your site's About section might want to know the Antix website seems to have been taken over by a spam system.
