That arises from longlong.h in gmp too (for the normal compiler, not
the build system compiler).  It's actually only a speedup, since an
error in the precompiling cpp automatically re-runs the plain cpp.  We
attacked it by adding -no-cpp-precomp if that option works, which is
probably safer than hard coding it.  (Though the test is still
restricted to gcc on powerpc*-*-*, to avoid junking up other systems.)
