Generate server-side GLX protocol decode functions using the 'make server'
target. The environment variable XORG_BASE must be set to point to the base of the X.org server sources where the files are to be placed. The 7.0.0 server release already contains files generated by these scripts. The scripts should have been committed months ago. Sorry for the lag. :(
