This isn't good! To prevent anyone else having this problem, it would be
nice if Allegro could autodetect the presence of this version of EMM386,
and use the low-precision version of the timer code if it is required.
Does anyone know how to detect the OpenDOS EMM386? Presumably just
detecting OpenDOS wouldn't be enough, as I imagine it can also be run as
a clean, non-multitasking environment where it would be better to use
the more precise version of the timer routines...

Of course, the ideal solution would be to fix the timer emulation in
this EMM386, if anyone has the time/inclination to work on that.
Although it complains about it, Win95 is able to run both versions of my
code, and I don't think we can let Microsoft get away with doing
something better than a free alternative! :-)
