I think this should fix it, but I haven't even tried to compile it.

A better fix is probably to add a variant of cpp_errno that takes a reason like
cpp_warning does. The current cpp_errno will then call this new variant with
CPP_W_NONE. These should be added to libcpp/errors.c and exported from
libcpp/include/cpplib.h
This should be an easy hack for someone to start contributing to GCC.
