Yes, that's the next obvious step.

That hardware should be fine. If you have other makes of PC around,
try one of those.

I'm not entirely sure, and it may not even be necessary if my reading
of the documentation is correct. Take a look at the GCC docs for the
i386 specific stuff. Adding "-march=i486" to the compile flags should
be safe, however.

Yep, that's correct. The fact that you can download the executable
shows that this has been built correctly.

If you are still having problems with other PCs, perhaps the next step
is for me to send you an executable I built here, and seen whether
that runs for you.
