Yes, that's exactly what I mean.

Why ? It's just another set of source files to be compiled as far
as the existing compiler is concerned. What the source code implements
does not need to match the language or language variant it is written in.

Until gcc 4.8, you could build gcc using just a C compiler, unless
you wanted Ada included, in which case you had to use an existing
gcc that also had Ada support built in (because the Ada frontend was
written in Ada).
