Re: Fix breakpoints when several source files have the same name

Sebastien,

Do you have a copyright assignment on file with the FSF? I cannot
seem to be able to find you in our records, at least not by using
your name. If you don't, then I am afraid that we cannot accept this
contribution until you do. This is a bit of a lengthy process, so
let me know if you need the request forms.

Overall, this looks OK to me (good catch on the FILENAME_CMP!).
I just have a few comments, little nits:

> +      /* Get symbol full file name if possible */

All comments should be full sentences, meaning that they should start
with capital letter, and end with a period.  The period should also
be followed by 2 spaces, so:

  /* Get symbol full file name if possible.  */

> +	if ((symtab->fullname != NULL)
> +	    && (symtab_to_fullname (s) != NULL)

You have unecessary parenthesis, and we avoid that in GDB (we find
that this makes the code harder to read - if only because it uses
a different style than usual).

	if (symtab->fullname != NULL
	    && symtab_to_fullname (s) != NULL
	    && FILENAME_CMP (symtab->fullname, s->fullname) != 0)

The function comment needs to be updated. Can you also put all first
3 arguments on the same line. The line break is unnecessary.

Same as above with the extra parens.
