To be frank, I do not understand much of the code in dwarf2read.c yet.
 However, I focused on functions and variables in my comment because
LOCAL and GLOBAL bindings in a file are present right in the ELF
.symtab section. If at all something is not being classified correctly
in GDB, then it should be a bug  (not necessarily in GDB?).  I did not
talk about types because they are treated as static when compiled as a
C program, and as global when compiled as a C++ program (in fact, I
thought this was Doug's concern to begin with!).

Overall, wrt this patch, what should we conclude?

Thanks,
