A future C-- test called T24474-cmm-override-g0 relies on the
GCC-specific behaviour of -g3 implying -dD, which, in turn, leads to it
emitting #defines past the preprocessing stage. Clang, at least, does
not do this, so the test would fail if ran on Clang.
As the behaviour here being tested is ``-optCmmP-g3'' undoing effects of
the workaround we apply as a fix for bug #24474, and the workaround was
for GCC-specific behaviour, the test needs to be marked as fragile on
other compilers.

Previously, C-- was processed with the C preprocessor program. This
means that it inherited flags passed via -optc. A flag that is somewhat
often passed through -optc is -g. At certain -g levels (>=2), GCC
starts emitting defines *after* preprocessing, for the purposes of
debug info generation. This is not useful for the C-- compiler, and, in
fact, causes lexer errors. We can suppress this effect (safely, if
supported) via -g0.
As a workaround, in older versions of GCC (<=10), GCC only emitted
defines if a certain set of -g*3 flags was passed. Newer versions check
the debug level. For the former, we filter out those -g*3 flags and,
for the latter, we specify -g0 on top of that.
As a compatible and effective solution, this change adds a C--
preprocessor distinct from the C compiler and preprocessor, but that
keeps its flags. The command line produced for C-- preprocessing now
looks like:
$pgmCmmP $optCs_without_g3 $g0_if_supported $optCmmP
