Am I to understand that you are not happy with the code?

You made two comments about the code:

  1. Fold multiple consecutive slash/backslash characters into
     single slash/backslash;

     To do that without modifying the source filenames, we need to
     allocate some memory locally to manipulate a copy of that filename.
     My take on this is that the file names we have seen, at least in
     the debugging information, have been consistent; and thus this
     enhancement would end up having no actual effect. I would wait
     until we come across a case where this is a problem before
     going that way. This is my opinion, and you may disagree...

     Note that this new function does pave the way for this sort
     of enhancement though, and I promise I will not object to a patch
     that implements your suggestion ;-).

  2. The possible introduction of a bug with certain locales because
     the function used in place of strcasecmp uses tolower.

     For this one, as I said, I don't know, and I'm not sure where
     to start looking for the answer. I'll be happy to modify the
     function body to do it any other way, if someone tells me how.
