" %-G%.%#had\ compilation\ errors.,  - Ignore the obvious.
" %-G%.%#syntax\ OK,                 - Don't include the 'a-okay' message.
" %m\ at\ %f\ line\ %l.,             - Most errors...
" %+A%.%#\ at\ %f\ line\ %l\\,%.%#,  - As above, including ', near ...'
" %+C%.%#                            -   ... Which can be multi-line.
