Well, _my_ answer is a firm YES, and whoever volunteers to make that
happen will get all the support I can provide in my admittedly limited
time.

IMHO, it's fundamentally wrong to compare file names as strings;
FILENAME_CMP is just a band-aid that I introduced as a stop-gap.  We
could (and probably should) do better, especially if situations like
above happen.

Alternatively, we could force GDB to canonicalize all slashes in its
symbol tables, and then FILENAME_CMP will work just fine.  But this is
less reliable, especially in the face of file names that come from
outside GDB, like from the command line etc.

I'd support that, but we need to talk a bit about what it should do,
as there are a few complications.
