What do you mean?  Does it do something?  Or does it not change anything
at all?   What have you tried and what result did you get?

With my patch (as opposed to the pre-patched code) compilation-parsing-end
determines the location from which to find the next error.

With my patch it first sets compilation-parsing-end to the place where you
clicked, which tells next-error where to look for the error.  The 0 arg
tells next-error to only look around that point rather than any line
further up or down.

[ I'm not sure what you mean by `fail', but I'll assume you mean that it
  goes the the first error in the buffer rather than the first in the last
  compilation. ]

Indeed.  But that's also how it worked in Emacs-21.3.
I'm only trying to fix the *new* bugs for now.
