I agree that though both patches relate to display of paths they are not
directly related.

I took a look at the original patch.  I it changes one place (in
backtrace) where we display symtab->filename.  There are several places
where we display symtab->filename, including the one I changed.

Either, (a) we plan to merge the original patch almost as is, in which
case it only changes the backtrace code, leaving my patch free to be
applied, or (b) we plan to extend the original patch to cover more/all
of the places we display symtab->filename, in which case, we'd have to
consider each of those places in turn and make a suitable change.

If (a) then my patch could go in, if (b) then it doesn't feel like my
patch changes things that much, I certainly don't add any new functions
or anything like that, that would make doing task (b) any harder later on.

I would be happy to take this approach as a compromise.

The frontend (eclipse in this case) wants to open the file in order to
display the contents.  Using just symtab->filename is not always
specific enough to identify a unique file.

I originally switched to only displaying the full path as this code is
only used for MI type output or when we fail to open the file, but I can
see that displaying the fullpath in addition might be cleaner.

Jan, if I post a patch that adds a fullpath would you be happy with that
as a solution?

Thanks,
Andrew
