_IF_ I understand what is being asked for here (two different source code
modules both defining the same global symbol name), then it doesn't matter
in Unix provided both symbols are the same size, and of the same type, as
the code in both modules will end up referencing the same memory area.

IIRC, if one symbol definition is of a different type, or a different size,
compared to the other symbol, doesn't the GNU linker issue an error during
linking ?
