It's a bug in gdb. I've tried everything I could think of to get gdb to 
see Pascal-style global variables (i.e., global variables which have a 
different name in the binary than what you use in the debugger), but 
it's simply impossible with the standard GDB on Mac OS X. You can only 
view them while stepping through code in the same unit as where the 
global variable is declared.

It's possible this can be solved with dwarf-style debugging information 
(as opposed to stabs, which is what we use now), but I haven't looked 
into that yet. Also, dwarf is only supported since XCode 1.5 (so it 
would preclude support for 10.1 and 10.2, unless people start building 
their own cctools)

No, it shouldn't be.
