	(fabs) [__cplusplus < 201103L]: Import from namespace std.
	* include/tr1/complex (acosh, asinh, atanh) [__cplusplus >= 201103L]:
	Likewise.
	* testsuite/tr1/headers/c++200x/complex.cc: Add std::fabs to global
	namespace before including TR1 headers.
	* testsuite/tr1/headers/c++200x/math.cc: New test.
