Hmm - storing the entire path is the standard behaviour (gcc stores the
path you give, whether relative or absolute), so that's OK.
But objdump should handle this better (I'm pretty sure gdb has no problems
with it).

gdb already supports backslashes doesn't it? (except for filenames passed
on the command line)
