The official reason was that COMDAT groups had been introduced in-between and 
that the patch should be rewritten to use them.  On my list, but very, very 
low-priority given the very, very low interest for this stuff outside the Ada 
world.

That would be a nice improvement.  I could try to propose an updated version 
of the GCC patch before the end of Stage 2 if you came up with something for 
the linker.

In the meantime, do you want me to apply the patch on Binutils mainline?  On 
Binutils 2.16 branch?
