Add a custom compiler to XCode 3.2

Question

I have a working gcc 4.3.3 toolchain for an ARM Cortex-m3 and would like to integrate it into XCode.

Is there a way to set up XCode (3.2) to use this gcc toolchain instead of the built-in GCC 4.2?

What I've tried so far: I've added a modified copy of the GCC 4.2.xcplugin and changed the name, version and executable path. It shows up in XCode but whenever I set the "C/C++ Compiler Version" to the custom compiler it fails with

Invalid value '4.3.3' for GCC_VERSION

It seems like the valid version numbers are hardcoded somewhere else because even when I remove the original GCC 4.2.xcplugin, the value 4.2 remains valid (but is not visible in the "C/C++ Compiler Version" drop down anymore).

FYI - I got gcc 4.4 integrated into latest Xcode 3.2.4 including flags - see blog at http://skurganov.blogspot.com/

I'm working on this myself.

Currently, it's looking like you have to inherit a built in compiler ref spec.

Adding a key of:

BasedOn = "com.apple.compilers.gcc.4_2";

Makes the plugin load correctly. However, there's the issue of invalid flags due to the apple specific compiler patches. I'm working on that part right now.
