The @dwarf test is because Mac OS X has two ways of handling debug information, (1) where we leave the debug information in .o files and use an associated "debug map" built by the linker - this is for development and provides fast turnaround since you don't have to link all the DWARF to build the executable, and (2) using a "dSYM" constructed by the DWARF linker (dsymutil). Since these are two pretty different modes of debugging, we run all tests both ways. But of course, dSYM's aren't available anywhere but OS X, which is why that test only gets run on OS X. I'd like to keep doing that for new tests, if you don't mind...
