Hello
There are two things here.
1- The list of compiler predefined macro can be found in
{Install}\Help\ColdFire_Build_Tools_Reference.chm
Look into sections "Predefined Macros" and "Coldfire Predefined Symbols" in there.
2- There might be some macro defined in the project itself when you create your project
using the wizard.
Check the "C/C++ Preprocessor" panel in your target settings for more information.
I hope this helps.
