--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
You are using -C, so what do you expect? Note that since 4.8.x GCC
automatically
includes stdc-predef.h (which you can see when you remove the -P option). The
comment nicely explains in the last sentence:
/* This header is separate from features.h so that the compiler can
include it implicitly at the start of every compilation. It must
not itself include <features.h> or any other header that includes
<features.h> because the implicit include comes before any feature
test macros that may be defined in a source file before it first
explicitly includes a system header. GCC knows the name of this
header in order to preinclude it. */
Thus, it works as designed. No?
