Then the problem is unlikely to be GCC. I'm fairly sure Apple's modified GCC 4.2 should work with their own OS and linker. Maybe the problem is with your GDB version, which you haven't stated. > Therefore, the linker must be adding the "signatures" to the linked module, > probably by reading the object decks AND the source files.

GCC doesn't have an associated linker, it is using the Apple linker that comes with the OS.
