By default, xrdb pipes the input file through cpp to define the following
symbols:

	HOST			current host name
	WIDTH			width of display in pixels
	HEIGHT			height of display in pixels
	X_RESOLUTION		horizontal resolution in pixels per meter
	Y_RESOLUTION		vertical resolution in pixels per meter
	PLANES			number of planes on the screen's default visual
	BITS_PER_RGB		number of significant bits in RGB color spec
	CLASS			default visual class
	COLOR			defined if on a color display.

You can get around this by using the -nocpp option to xrdb.
