[Xquartz-dev] X11 developer updates?

[Dave Ray]

Since I occasionally compile my own X11 programs, I was wondering if  
there are any updates outside the X11.app beta distribution that I  
should try to use, such as headers, libraries, etc., and what would be  
the best approach for me to update those. Or should I stick with the  
stock Apple development libraries. I think my X11 development  
environment is from the 10.5-X11 Developer distribution + 10.5.4 +  
10.5.5 updates. TIA
