That has been my thinking, but perhaps it does make sense to make that 
change with the C++0x library deployment; the impact should be pretty 
limited.

I'm surprised to see that EDG doesn't mimic this bug in G++ 
compatibility mode; in fact, they get mangle22.C wrong in a different 
way.  The symbol should be

_Z1g2CBIL_Z3foocEE

-fabi-version=2 gives

_Z1g2CBILZ3foocEE

and EDG 4.1 gives

_Z1g2CBIXL_Z3foocEEE

(extra X/E around the name even though it's an expr-primary).
