--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Seems to be a user error. Just read man page of cpp and gcc, the former
accepts (besides options) just two arguments, infile and outfile, while grub
clearly relies on $(CPP) being able to preprocess many source files at the same
time.
That is gcc -E, not cpp (and if you don't override it from the command line,
that is indeed what the configure will do correctly automatically).
