OK, how about this, against trunk?  Tested on x86_64-linux-gnu.

Thanks,
Richard


include/
	* longlong.h: New file.

libgcc/
	* longlong.h: Delete (moved to include/).

libquadmath/
	* Makefile.am (AM_CPPFLAGS): Define.
	* Makefile.in: Regenerate.
	* printf/gmp-impl.h: Remove path from longlong.h include.
