Upgrades to Xcode 4

[GoogleCodeExporter]

What steps will reproduce the problem?

Please set the default GDataFramework SDK to 10.6. (CurrentSDK == 10.7 and 
x86_64 generates errors during headers precompilation, I've not verified the 
cause)

Add the following line to both Debug and Release OSX targets, since llvm 3.x is 
not supported on PPC:

"GCC_VERSION[arch=ppc]" = com.apple.compilers.llvmgcc42;

Thanks.
Mirko
