Through the C compiler, but otherwise yes. I've posted the compiler invocat=
ion
in comment 0 verbatim.

Yep, because trad.exp adds -traditional-cpp, as intended. But I don't run t=
he
testsuite, but rather use its test cases as part of my larger test corpus,
compiling every individual case in that corpus with randomly chosen compiler
options. IOW, my testing ignores DejaGNU directives in gcc testsuite (which
means it also often ignores common sense when choosing compiler options, as=
 a
consequence).

I can further describe my setup if you are interested, but it's off-topic in
this PR.=
