Being a C programmer, I always missed not having support for cscope "out
of the box" in my vanilla Emacs.  It is unfortunate that xcscope.el is
not part of Emacs proper.

Here is a quick and dirty means to alleviate this drawback and make
cscope "one another" search engine (similar to rgrep etc).

This bug is a continuation of my earlier bug#13459.  Ideally I want to
be able to see the "function context" in search results.  See earlier
screenshot

I have more ideas on how the symbol searches could be imporved in
Emacs.  I will document these in future bug reports.

For a first cut, the following works.  Update
`compilation-error-regexp-alist-alist' as below.
