Xcode 4 gcc-4.2 failed with exit code 1

Question

Any idea why my build is failing on the following process? I have 2 other targets in this project that build just fine. I cannot see any clear reason based on this what the issue is. I've compared all the build settings in each target and all seems to be well/the same.

Any help is appreciated.

Ok, figured it out. I had a preprocessor macro for this target that started with a number e.g. "123TEST", evidently the compiler does not like numbers first, "TEST123" works fine.
