[Wine] "Support for shared 32/64-bit setups" ?

[StringCheesian]

Does that mean a single prefix for both 32 bit and 64 bit apps?
Does it mean a single installation of wine for the same?

Well, however it works it's a good idea. I think a lot of 64 bit Windows apps right now are actually 32/64 hybrids that do install some 32 bit stuff too. Especially suites of multiple apps.

I just thought we're more likely to get an answer here.
