bug#10727: 23.3; compilation-next-error misinterprets gcc errors with column info

[code]

Newer versions of gcc supply the column and line number of errors by
default. This causes the next-error command to fail to interpret the
filename in some cases.

To replicate:
* Create these files: 
       test.cc  which contains:
                 #include "test.h"
       test.h   which contains:
                 calss a();

* M-x compile with an argument "g++ test.cc", using a version of gcc
  that outputs columns (4.5 and higher does for sure).

* The compilation buffer will contain:

-*- mode: compilation; default-directory: "/Users/patrik/" -*-
Compilation started at Sat Feb  4 13:50:36

g++-fsf-4.6 test.cc 
In file included from test.cc:1:0:
test.h:1:1: error: 'calss' does not name a type

Compilation exited abnormally with code 1 at Sat Feb  4 13:50:36

* now do next-error (C-x `). The minibuffer will display:
  Find this error in (default test.cc:1):

Expected behavior is that it will find the error in test.cc. Doing
next-error again will correctly find the actual error at test.h:1. It
seems to be only the "In file included from..." errors that are
mis-parsed. 

I have tried to trace this in the debugger but have only gotten to
the macro compilation-loop in the compilation-next-error function in
compile.el. It seems the error is in how the properties are set in the
compilation buffer, because apparently these functions only look at the
test properties. 

A workaround is to use the argument -fno-show-column to gcc, but the
column numbers are actually useful so it would be nice to have this work 
correctly.
