-Bgroup?

[Henry]

I am trying to use -Bgroup, but it doesn't seem to be working. For  
example, I have libA and libB and they both have function theFunc().   
What is happening is that a function in either library will theFunc()  
from whichever library was loaded first. The behavior I would like is  
for if a function in libA calls theFunc(), it calls libA's theFunc(),  
and if a function in libB calls theFunc(), it calls libB's theFunc().  
As I understand it, -Bgroup is supposed to do this, but it doesn't  
seem to do anything. Does it not work with C++?
