The C++ front end makes pedwarns into errors by default (unless -fpermissive).
However, this only applies to front end pedwarns and not to preprocessor ones,
as the preprocessor has its own pedantic_errors setting which is changed by an
explicit -pedantic-errors option but doesn't default to 1 for C++ the way the
global setting does.
There should be a consistent pedantic_errors setting for both compiler and
preprocessor pedwarns.
Test: preprocess a testcase such as
#if 1
#endif 1
and observe it gives a warning which becomes an error with -pedantic-errors,
whereas by the principle followed by the C++ front end it should be an error
which becomes a warning with -fpermissive.
