Yeah. However, selecting different PG_PRINTF_ATTRIBUTE values for
C and C++ mode seems to get the job done. I've confirmed the attached
silences these warnings for me when mixing-and-matching gcc and clang.

I don't have a lot of faith in the meson.build addition being correct,
though it worked in a simple test. Anyone want to review that?
