Clang is right to reject this. ABS is looked up at template definition time
(which finds nothing), then augmented by the results of argument-dependent
lookup (which does not add anything, since "float" has no associated
namespaces).

GCC does extra lookups not permitted by the C++ standard, and therefore accepts
this ill-formed code.
