 It's a bug in GCC 3.3.  It has been fixed.  If you require 
bug-compatibility, you may maintain it yourself either by fixing GCC 3.3 
or by using your workaround.

 We don't expand the ABI every time a bug in a tool makes it go beyond 
what's already defined.

 In a perfect world GCC 3.3 wouldn't have had this bug.  Is backporting 
the fix from GCC 3.4 impossible?

 Forcing the right bug fix instead of attempted workarounds?
