Language: C-like foundation grammar for C/C++ grammars

/* In the future the intention is to split out the C/C++ grammars distinctly
since they are separate languages.  They will likely share a common foundation
though, and this file sets the groundwork for that - so that we get the breaking
change in v10 and don't have to change the requirements again later.
