We do not know of any ABI changes between 3.2 and 3.3; the goal is for
the two compilers to be compatible.
There have been a couple of bug fixes which affect mangled names, but
those are due to situations where the 3.2 compiler was not a correct C++
compiler, rather that situations where the ABI was changed "for fun".
