Welcome to C++.  You've just violated one of the rules of the lanuage
for which there is no warning or error message.  This is not a bug, it
is how C++ is.

You can use static to tell the compiler that you don't want any
linkage between the two.  The use of static is covered in manny books
on C and C++.  Beyond this, you can use namespaces or classes to solve
the problem as well.

This is more about how to program in C/C++, and comp.lang.c++ would be
a better forum.
