Sure, understood.

I've spent some time thinking about this ABI change, back and forth, and
even produced the obvious patch (to use 'GOACC_FLAG_IF_PRESENT',
'GOACC_FLAG_FINALIZE'; attached for posterity), but in the end I'd like
to withdraw, and keep the current ABI.  (..., and I'll instead follow up,
at a later point in time, with some documentation updates and code
restructuring, to make this better understandable/maintainable.)
