Subject: [PATCH] Remove CPPFLAG -I/usr/X11R6/include in all example Makefiles
 None uses X11 directly, this is only needed in the Library itself. Also this
 was even added on all platforms while many don't even have X11. Thanks
 @Isomorphix noticing something off about that once (a long time ago...):
