I just checked in some code into the AUCTeX CVS that should deal with
file-line-error style messages in preview-latex.  This will not help
with AUCTeX errors, though, and I am not sure that it will work in
multiple-directory situations right now when the file names in the
error messages are relative.

It might make sense to try to propagate the respective changes, or at
least the patterns, to AUCTeX's error handling.

Takers?  Redirected to auctex-devel...
