Omitting unused global variables

[piccolo]

I think that this is based on the optimizer. If it isnt set properly then the code stayes in the obj file and thus it gets linked. This behaviour is at least not strange to me. I was more amazed that delphi does properly optimize more things out...
Anyway you should check the object file and you see it is one block of compiled code. Now if those two functions are in a second .c file and also compiler then they will not be linked indeed...
