Afaik 64-bit windows doesn't support 16-bit binaries, so I just
assumed Wine wouldn't do it either on x86-64. Not for any real
technical reasons, though.

HOWEVER. I'd like to hear something more definitive than "I haven't
tested recently". The "we don't break user space" is about having
actual real *users*, not about test programs.

Are there people actually using 16-bit old windows programs under
wine? That's what matters.
