I wouldn't expect the *uninitialized* data to have any effect on the size of 
the .out file, either. The contents of the .o files are combined to create 
the .out, and I don't think the uninitialized data appears in it, either, 
just being a length given to the system loader. (That's definitely how it 
works on Windows, and Windows NT copied [not very well] a lot of Unix stuff, 
mainly because they started with an existing Unix targeted C compiler.)
