It looks like there's a lot of hardcoded stuff in `msgwindow.c`.

Some of these functions look relevant on a quick scan:

* msgwindow.c:801: parse_compiler_error_line()
* msgwindow.c:248: get_color()
* msgwindow.c:1189: show_build_result_message()

I'm not really too familiar with that code though, so maybe there is an 
easier way than hacking the source.
