Thanks again Juanito.
Still so much to learn <embarrassed x 2>:
- Didn't realize Apps is case-sensitive, x.h 'provides' so many hits eyes glazed over, X.h search much better
- Forgot TC 5 used same version Xorg, so makes sense it's in TC 5 repo, sorry for being a doubter
Successfully built latest dwm, PMed original maintainer and may submit shortly, not around since TC 4.
