--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Preprocessing discards information, so obviously lots of warnings are affected,
by not being able to track the preprocessor macros, by seeing the tokens coming
from different locations, or by comments used e.g. for -Wimplicit-fallthrough
being discarded.
You can use -fdirectives-only -E preprocessing instead, which keeps macros as
is.
