Yes, I guess that's first in the include search path. Since w32api now provides a that header, we should probably stop providing it in libGL-devel. > I replaced that one and the code in > /usr/src/xorg-server-1.14.3-1/src/xserver-cygwin-1.14.3-1/hw/xwin/glx > now compiles.

It's not really the function of that document to tell people how to install packages on cygwin. I don't really want to put the package list there twice and have to keep both copies updated. If you're doing the package installation manually, you just find them (perhaps using the search function), and select them for installation. -- Jon TURNEY Volunteer Cygwin/X X Server maintainer
