FAIL: libgomp.c/omp-loop03.c execution test
FAIL: libgomp.c++/loop-3.C  -O  execution test
FAIL: 29_atomics/atomic_flag/clear/1.c execution test
FAIL: 29_atomics/atomic_flag/test_and_set/explicit.c execution test
FAIL: tr1/8_c_compatibility/complex/overloads_float.cc (test for excess errors)
FAIL: tr1/8_c_compatibility/complex/overloads_int.cc (test for excess errors)

and possibly

FAIL: abi_check
