`-fabi-version=N'
Use version N of the C++ ABI. Version 2 is the version of
the C++ ABI that first appeared in G++ 3.4. Version 1 is the
version of the C++ ABI that first appeared in G++ 3.2.
Version 0 will always be the version that conforms most closely
to the C++ ABI specification. Therefore, the ABI obtained
using version 0 will change as ABI bugs are fixed.
The default is version 2.
This appears to imply that there were no ABI changes between 3.0
and 3.1, and between 3.2 and 3.3.
