I would think it more likely that there would be a bug, either in
gcc's encoding of them or in gdb's processing of them. And if the
code is duplicated, then both locations need to be modified to fix the
bug -- with the attendant risk that someone will modify one and forget

I don't know how people would feel about having STABS have a
description of the encoding combined with a caveat that the DWARF
2.0.0 spec is authoritative. I would certainly prefer that the STABS
document remain self contained.
I think this is a good strategy. It's already a ``gcc extension'', and

Have you thought about link time information compression? One of the
complaints leveled at the macro stuff is the size of the resultant debug
