[webkit-dev] If you're on Mac, please upgrade to Xcode 3.1

[Maciej Stachowiak]

Hello WebKit folks,

We'd like to change some WebKit components to build with GCC 4.2 by  
default on Leopard, for better performance. Unfortunately, this  
compiler is not available on the system by default, so everyone  
building on Mac will have to switch to Xcode 3.1 by default.

We will probably start with a soft switch, where GCC 4.2 is used only  
on Leopard if you have Xcode 3.1, but eventually it will become a hard  
requirement so I recommend upgrading sooner rather than later.

Regards,
Maciej
