Can I have a macro which is different in different parts of the code, eg #define Mac Something .... #undefine Mac #define Mac SomethingElse ... Mac would be something used by other macros. Is there any way of doing something like this?

Yes you can, but if I recall correctly, you use
#undef MacroName

to undefine it. You can also test if the macro is/isnt defined with #ifdef or #ifndef

#ifdef MacroName
//do something if the macro is defined
#else
//do something if the macro is NOT defined
#endif
