OK, I'm trying to understand:

3.2 generates the same mangled name for some different types.

3.3 generates no code for the 3.2 ABI: due to a defect in the G++ 3.2 ABI, G++ 
has assigned the same mangled name to two different types. When linking 3.3 
code against 3.2 code nobody would know what happens.

3.3.1 generates some code for the 3.2 ABI. But when linking 3.3.1 code against 
3.2 code still nobody would know what happens (I assume ;-).

Isn't ABI compatibility all about linking code compiled with different 
compilers?
