Ok, I didn't love any of the patches I saw for the qnx4 problem, so I
silenced that warning with a new patch of my own. Like the sparc64

code is actually doing.

thanks, looks good to me, too!

Looking at the qnx4 code-base history, I don't think it has gotten any
actual development outside of cleanups in the git history timeframe,
which makes me suspect nobody uses this code.

But hey, maybe it just works so well for the very specialized user base ...

it's actually the latter (although I guess the user base is shrinking)
