Yep, X tends to #define lots of very generic things (like "Status" or  
"Picture") which causes breakage if they're used in pretty much any  
context (e.g. C++ member function name, enum value, parameter name,  
etc.).  In general, a file that includes X libs shouldn't include  
anything from any other platform, or pain will result.  You can try  
#undef'ing all the bits that it's complaining about..

Yeah, but in cairo no file ever includes both X and quartz includes.   
(Or X and win32 includes, where a similar collision appears.)
