It would be better to just avoid the use of glXGetCurrentDisplay[EXT]
altogether.

AFAICT, the OGSF library should not be using any glX functions, or
even any X-specific functions.

The version in 5.0.2 doesn't use a single Xlib or glX function; it
uses functions from other GRASS libraries, TIFF, GL/GLU and ANSI
functions from libc/libm, and so should be completely portable (i.e. 
the 5.0.2 OGSF library should work with a native Windows version).
