Subject: bug #230 Revert to Xinerama 1.1 In order to make a "quick" release it
 has     been decided that the priority is to preserve the server's internal  
   API/ABI so that third-party drivers that depend on symbols like    
 noPanoramiXExtension, etc., would not need to be recompiled. Too bad     gcc
 on Linux doesn't support ELF's weak symbols as that would have been     a
 reasonable solution for preserving the ABI. N.B.: While symbols, i.e.    
 functions and variables revert to the old name, I did not revert build    
 names, i.e. -DXINERAMA, to the old -DPANORAMIX. There was no need, and    
 it's just a build issue that has no impact on the binary output of the    
 build.
