The C preprocessor is most certainly part of C, and the fact
that it may be implemented as a separate program is not
relevant (except that, as noted, it may mean that in practice
it can be used for other languages).

Note that there are other possibilities, including

generalized macro processors (some of the GNAT tasking
development was originally done using the M4 processor).

specialized Ada preprocessing tools. GNAT supplies a tool
called gnatprep, and you will find that other vendors have
similar tools. In fact gnatprep is really pretty much
independent of GNAT and could be used with any Ada compiler.
(or for that matter, any C compiler :-)
