--- Comment #2 from Walter Bright <bugzilla at digitalmars.com> ---
ImportC does not has builtin, and those macros are predefined by cpp.
Therefore, cpp is run with -Wno-builtin-macro-redefined.

Perhaps you are building with an earlier dmd? That -W switch was added to dmd's
call to cpp very recently.
