Hello
According to ColdFire_Build_Tools_Reference.pdf, typeof operator can be used only when GCC extension is enabled for the compiler.
To enable GCC extension check "Enable GCC Extension in the target settings "C/C++ Language" Panel.
I did try the macro you have provided with CodeWarrior for Coldfire V6.4 (I do not have a V6.3 installed any more) and it is working well.
