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?
