Iphone SDK 3.0 UIKit Error

Question

Hi I am using iphonesdk_3.0_beta5 SDK. When I try to compile my code using simulator 3.0 option I get following error. The code compiles for rest all simulator option ie 2.0, 2.1, 2.2, 2.2.1 While compiling my code I get following error
from /Users/videomac/manish/EXPLab/2009-05-27-11-20 myAppLL_2/myAppPrefix.pch:7:
In file included from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0 .sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKit.h:30,

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0. sdk/System/Library/Frameworks/UIKit.framework/Headers/UILocalizedIndexedCollatio n.h:21: fatal error: method definition not in @implementation context
The errors are located in file UILocalizedIndexedCollation.h which is SDK file.I am using UIKit Framework of SDK 3.0. Can anyone tell me what should I do to remove this error?

I've traced this problem to be the compiler version being used. From what I can tell, REDACTED requires GCC 4.2 while iPhone SDK 2.x only works with GCC 4.0.
Here's a way to fix this.
In your Target Info, select Build separator and look for the section Compiler Version. Then:
1. Select the C/C++ Compiler Version
2. Set the default to GCC 4.0
3. At the bottom-left control, hit Add Build Setting Condition
4. On the left, choose 'Device - iPhone OS 3.0'
5. On the right, chose GCC 4.2
6. Repeat steps 3 to 5, now with 'Simulator - iPhone OS 3.0' on step 4.
