# This is a bit messy.  We want this libGL to be capable of loading old
# interface drivers, so we have to turn off DRI_NEW_INTERFACE_ONLY.  However,
# glcontextmodes.c is built elsewhere with DNIO on, so we symlink it across.
# 
# Furthermore, context creation has evolved over the years, such that this
# code will not build with DNIO defined.  When we finally drop old interface
# support in libGL, we need to clean up both glxcmds.c and dri_interface.h.
