PS1, Line 4: ${WARNERROR-yes}
Maybe just add a colon. so that it is very clear? I mean
 ${WARNERROR:-yes}

Official instruction in Makefile says "If your compiler spits out excessive warnings, run make WARNERROR=no". I spent some time thinking what is going to happen if WARNERROR is empty, but then I thought, better make it clear instead of thinking.

Otherwise all good.
