Thanks for the review.  I'm not aware of any examples without #line.

While dwarf doesn't understand inodes the paths do have some canonical
behaviour.  e.g. As I understand it, posix says //tmp/foo == /tmp/foo.
 I recognize the paths are from the compilation host not the debug
host, we could write a path canonicalizer.

But no matter, I can certainly pursue a different fix for the problem
at hand, perhaps by adding an option to gcc to set DW_AT_comp_dir.
