It sounds like the OP is, so far, in a research project.

But also seems to want something like C++, but without all the
fancy new features.  Starting with a compiler without those features,
seemed like a good way to go.

(I believe some have suggested, over the years, a C--, though
exactly which features are removed, I don't know.)

The process for starting with copyright code, and modifying it
until all copyright parts are gone, seems to be well known, though
I suspect never easy.
[I wouldn't try mutating out the copyrighted stuff.  Depending on how
aggressive the copyright holder is, they can claim copyright in the
structure and sequence of the code.  And if it's a research project,
it's not that hard to make a parser and symbol table using compiler
tools better than 1997 era yacc. -John]
