[Wine] Reverting from sour wine

[John Drescher]

> Wine only really became effective at running Windows Mathematica at 1.3.17 (or thereabouts). Therefore I try to use the latest version of wine, but I sometimes wonder how easy it would be to back off to a previous version (but not to 1.2) in the event of problems.

The ease of downgrading versions of wine depend on what OS you use or
if you build from source.
