FYI. I told them that this won't be accepted on NetBSD, but the
working group is doesn't seem to be willing to change this.

Subject: OpenGL headers and libraries out of place

The OpenGLŪ Application Binary Interface for Linux
requires that* lives in /usr/lib and gl.h lives in
XFree86 v4.0 ships with all these files in the /usr/X11R6 tree.

This standard exists to ensure that all 3D applications can easily
find the OpenGL headers and libraries they need, and it would be a
major disservice to Linux if we didn't follow it.

Do other people have views on whether XFree86 on other platforms
should leave these files in /usr/X11R6 or put them in /usr/lib +
/usr/include ?

My initial thought is that *BSD may wish to follow Linux, but that
platforms which provide their own OpenGL implementation (eg Solaris)
may have good reasons not to follow Linux.
I guess it is a Unix-centrred assumption that /usr/lib and
/usr/include are even "standard places" true on all supported
platforms ?

I would tend towards having installers *not* replace existing
versions of these files with the XFree86 versions, not least
because at present there are 2 features present in stand alone
Mesa which are missing from our libraries.
