Cannot build iPad app for the simulator

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open the CPTestApp-iPad project.
2. Build for the simulator

What is the expected output? What do you see instead?
Before the update to iOS SDK 4.1, this project built and ran fine. After the 
update, it won't build for the simulator. Every source file in the Core Plot 
project generates the following error:

<command-line>: error: "__IPHONE_OS_VERSION_MIN_REQUIRED" redefined
<command-line>: error: this is the location of the previous definition
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 
failed with exit code 1

I'm still running into this issue when compiling for an older SDK that the 4.1. 
but only for the simulator,  Any idea ?

You can edit the Core Plot project build settings if needed. Change the "iOS 
Deployment Target" to whichever earlier version you're using.

I'm now having the same issue after upgrading to iOS 4.3 SDK. Everything worked 
fine prior, but now I'm seeing the "__IPHONE_OS_VERSION_MIN_REQUIRED" redefined 
error.

I tried switching all project iOS Deployment Targets to 4.1 (while using iOS 
4.3 base SDK), but no luck.

Anyone else experiencing the same issue?
