This is where this goes fail. Sorry, it is not acceptable to introduce
an ABI on x86-32 without providing it also on x86-64 in compatibility mode.
I also don't believe it is not possible... it might require some more
cleverness; perhaps we need to do the 32-bit vgtod in such a way that it
*is* compatible with 64 bits.
