| I am trying to detect the server type in my resource file:
| 
| 	#if VENDOR == "MIT X Consortium"
| 		....
| 	#endif
| 
| But my test in the resource file fails:
| 
| 	% xrdb -merge resourcefile
| 	34: syntax error (in preprocessor if)

  That's because cpp only knows how to compare numeric constants with
"==".  You'll have to think up a way to cast what you want to do into a
numeric or boolean (#ifdef) domain.  You can't compare strings.
