CVS: Requiring CC on C++ sources

[Akim Demaille]

For some reason I have not tracked down, the current CVS version

(ChangeLog: 2003-02-24  Alexandre Duret-Lutz  <address@hidden>

        * ChangeLog: Move 2002's entries to ...
        * ChangeLog.02: ... this new file.
        * Makefile.am (EXTRA_DIST): Add ChangeLog.02.)

wants AC_PROG_CC if I use cppgen-visitor.hh as a library source file.


Here is a test case.  Sorry for no going further into it :(
