I am trying to detect the server type in my resource file:

	#if VENDOR == "MIT X Consortium"
		....
	#endif

This is based on the predefined symbols in xrdb:

    % xrdb -s
     -DHOST=unix -DSERVERHOST=unix -DCLIENTHOST=tone -DVERSION=11 -DREVISION=0 -DVEN
    DOR="MIT X Consortium" -DRELEASE=4 -DWIDTH=1152 -DHEIGHT=900 -DX_RESOLUTION=3545
     -DY_RESOLUTION=3543 -DPLANES=8 -DBITS_PER_RGB=8 -DCLASS=PseudoColor -DCOLOR

But my test in the resource file fails:

	% xrdb -merge resourcefile
	34: syntax error (in preprocessor if)

Why?


System: X11R4, SunOS 4.0.3.c, Sun4

BTW, how can I store a symbol in the resource data base - permanently?
In
	%xrdb -Dsym=value resourcefile
the definition of `sym' lasts only for this single run.
