This is possible through winecfg.  However, I agree that this should be packaged
with Wine based upon customer usage.  There are certain programs that need to
run in Windows NT, or Windows98, not WindowsXP.

We need to avoid these types of tricks.  Microsoft did some things to prevent
certain applications, which complete with their
products, from running as best as they can or even to prevent them from running
in the first place.

Note:  Your original request definitely has merit, but serious investigation
should occur before implementation efforts start.

Yes and no.   Annoying some versions of vb need the api to malfunction in a
particular way or they don't work.

IgnoreVBOverflow shim "Some VB apps try to store win32 handles in WORD size
variables. On Win9x this works because most handles are 16-bit. However, on NT,
the VB type checking code throws a ?Runtime Error 63. The shim intercepts the
type checking code and ignores the check."

Most of the needed ones are like this.   If active disregard this check.  If not
active check for this defect.

TerminateExe shim This compatibility fix terminates an executable (.EXE)
immediately upon launch.

I don't think we need that one.

Yes shims are like our app controls but they are more direct effect on what the
api is.

Basically wine's does not have to be a shim system as such but current level
of controls for application compatibility are a bit lacking.  Of course I would
say these controls limited to what MS shims provide not just shims to work
around wine code bugs.
