The Windows headers provided by MinGW define MOD_SHIFT. Avoid
it by using SPITZ_MOD_* for our constants here.

The other approach would be just to #undef MOD_SHIFT, (and
looking back through the archives I see Stefan posted a patch
to do just that last year) but I think it's cleaner to do this.

I replaced a few of the /* apostrophe */ keysym names with
the symbols just to keep us under the 80 column limit...

That would probably be the nicest approach, yes. I won't apply
this to the target-arm queue just yet.

I'm wondering if we might be able to get to the point of enabling
-Werror for Windows and MacOSX builds. Do you think that would
be a useful thing to do? (Obviously for git builds only, same as Linux.)

(For MacOSX there are some deprecation warnings in the audio
code I need to fix first but we otherwise compile pretty much
warning free on 10.8. I'd be reliant on reports from other people
for warnings on 10.9 and on earlier-than-10.8, though.)

thanks

I see the patchset to try to reduce the scope where windows.h
is pulled in got a bit bogged down in review. Stefan, are you
still planning to move forward with that, or should we maybe
just apply this patch fror now? I think this is the only w32
build warning currently...

thanks

I'm going to put this patch into target-arm.next, because
I'm bored with seeing those MOD_SHIFT warnings go by...
