A bit off topic, but I'd like some clarification on this.

Am I understanding correctly that `WINEARCH=wow64 wine somewin32.exe` will use
the new wow64 mode, while anything else will use the old one? Does it matter
how the prefix was initially created? (Does it work in an existing win64
prefix? Does it work in an existing win32 prefix? Is there such a thing as a
wow64 prefix?)
