	PR bootstrap/35051
	* double-int.h: Don't include gmp.h for GENERATOR_FILEs.
	(mpz_set_double_int, mpz_get_double_int): Hide from GENERATOR_FILEs.
	* real.h: Don't include gmp.h or mpfr.h for GENERATOR_FILEs.
	(real_from_mpfr, mpfr_from_real): Hide from GENERATOR_FILEs.
	* tree.h (get_type_static_bounds): Likewise.
