--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Heh.  Does this since 4.8.  This is from stdc-predef.h we forcefully include in
each translation unit.  You can use -nostdinc to restore original behavior.

Note that this bug will likely be closed as invalid/wontfix.  OTOH the included
comment says the file is LGPL which may have issues if it gets included in
sth statically linked?  I think we should change its license to BSD/MIT.
