Hi Max,

This is because "common" variables do not have single place where they are
defined. At least not in object files. They can be defined in multiple
locations, and it is only once they are linked that a final size and place of
definition is chosen.
If you look at the object file nm's output will show the variables of type "C".
But once the object file is linked their type changes to "B", as they now have
a definite location and size.
Cheers
Nick
