well, the problem is that until the mono guys and us audio freaks came
along, wine was a "self-contained" project. wine was the only thing
that used the wine APIs. but now the situation has changed, even if
only by the smallest amount. you've got at least 2 projects using wine
API's outside of wine.
in our case, the specific problem is the addition of the "environment"
ptr arg in wine_init(). there appears to be no way to check on whether
this needed, hence:

how can anyone know which version of wine_init() to use, then?
