	* c-omp.c (c_omp_declare_simd_clauses_to_numbers): If all clauses
	are to be removed, return NULL rather than original clauses list.

	* decl.c (grokfndecl): Handle flag_openmp_simd like flag_openmp.
	* pt.c (apply_late_template_attributes): Likewise.

	* g++.dg/vect/vect.exp: Run also simd* tests.
	* gcc.dg/vect/tree-vect.h (abort, exit): For C++ use extern "C".
	(check_vect): Fix up get_cpuid call for C++.
	* g++.dg/vect/simd-clone-1.cc: New test.
