You certainly can build and run testcases with Apple's compilers to
compare behavior (without looking at the sources), just as people looking
at C++ tests exercising corner cases of the standard routinely compare
with how EDG handles those areas (without having access to EDG sources).
Independent implementations are of value in deciding how a language should
be defined if it is not to be a language permanently defined by a
