app-misc/hilite is a utility which highlights stderr text in red see the attached patch for emake
Created attachment 96665 [details, diff] patch to add hilite to emake
considering the history we've had with output parsers, i'd say no ... you can easily do 'export MAKE="hilite make"' in your make.conf
i just considered it for convenience, but if there are/were problems with output parsers this should probably be WONTFIX...
