I guess. I think part of the reason it seems wrong to me is that there is a 
platform id called 'APPLE' (different case) and a variable of that name

There is also an existing GNU platorm/compiler id (same case).

If the same name is to be used, is there any reason not to use the same 
case?

Thanks,

Steve.
