As Chris pointed out, I would see http://llvm.org/svn/llvm-project/clang-tests/trunk/gcc-4_2-testsuite/README.txt for directions on running the test suite.  I believe your assumption about dg-warning is correct, but I'm by no means an expert of how the nightly testers work.

The other is a comparison of an array and NULL.  Is this warning appropriate here or should these cases be excluded from the warning?

Seems like a reasonable guess.  Unfortunately, I don't know the intent of your patch or the expected output from the individual test case, so I can't really voice an opinion on the matter.  Once you get the test suite running locally you could try modifying the test case by adding the appropriate dg-warning "" markers.  If this fixes things and you are confident the emitted error message is correct then you could submit a patch to the test case to make the buildbot happy.
