I started from scratch.  The code is not limited by any pre-existing licence.
It is also unusable except in my still-unfinished-but-slowly-getting-there
Smalltalk->C compiler.  Some parts of it have been tested in Squeak, but it's
painful; I don't have a .cs generator yet.  Should be doable, mind.  It's
based on the ANSI specifications, with a little creative reading between
the lines where the ANSI specification is incomplete or inconsistent, which
it too frequently is.

I am still learning a lot by doing this.
