Done, thanks to you both for feedback.

Don't worry about it. If you get the chance, however, I would like some
feedback on what to do with the "C" header issue. At this point, when
you configure and build for QNX, do you pass in a --enable-cheaders=c on
the configure line? Does it mostly work, or are additional tweaks
necessary? If so, do you mind sharing them?

What kind of testresults do you get, out of curiosity?
