At least with GCC and with Unix and DOS style of EOLs, there's no
basis to assume that line numbers will be ``totally out of wack''.
The Mac case obviously is harder, but it sounds like that style is
dying anyway.

GCC supports both Unix and DOS EOLs on Windows as well.  So, at least
for these two styles and platforms, it's possible to support line
numbers reliably.

All of them might be impossible, but some of them could be quite
possible.

Anyway, unless we have a volunteer to add this kind of support to GDB,
this dispute is purely academic.
