hmm.. CW -> gcc is a piece of cake in comparison to the other way
around :) gcc -> CW is a nightmare, as you need to recreate all the
resources in constructor and get the resource #defines correct :)

seems like it doesn't like your globals :) could be a problem
with the way you are building? what do you see when you type
'make'? a list of commands might help us sort it out :)
have you thought about using a #define for these constants instead?
#define appCreator 'Razr'
#define appVersionNum 0x01
thats how i have been doing it since day one.. is there a need to
store them in a global variable? they are obviously not going to
change, so might be best to declare as constants :)
