That sounds to me like filing a bug in Firefox and someone replying to use
Konqueror instead. :)

Yes there are alternatives, but a bug was filed so it can be fixed. The Wine
project also includes the DOS subsystem, which is why it has the winevdm and
winedos modules.

There are advantages to having a single program (e.g. Wine) run both DOS and
Windows programs. First is that an .EXE extension can either be a DOS or
Windows program. CLI people do not understand this need, but GUI people like me
need to have an extension mapped to a particular program, so that clicking it
would open the associated program. I once downloaded an astronomy software I
needed, and not knowing it was DOS-based, double clicked it. Nothing happened.
Clicked again and still nothing. KDE System Guard then showed multiple
instances of winevdm in memory waiting to be killed. I don't think this is
desirable behavior.

Second is that there are Windows programs that are frontends for DOS programs,
and if Wine couldn't open the DOS program, will cause the Windows program to
hang.

Now, if Wine could only automatically invoke DOSEMU whenever it encounters a
DOS program (assuming DOSEMU is installed) and pass on the command, then that
would solve my problem of which program to associate the .EXE extension.
Additionally, perhaps binfmt should also learn to pass on DOS programs to
DOSEMU and Windows programs to Wine. If this is not possible then Wine should
fix its DOS support.
