This looks pretty easy to include, but it ought to be decided
automatically.  It's possible to put ad hoc code in configure if necessary,
though if there were some predefined preprocessor symbol that would be
better.

Does the configure test for this not work?  You should get something like

checking whether getpgrp takes no argument... yes

and config.log should say why it failed, if it did.

Is it enough to test
#if defined(SGTTYFLAG) && defined(SGTABTYPE)
?

Likewise, can we just test directly for these flags being defined?

This looks like something we need a preprocessor definition for.  If there
really isn't one (_QNX_, _QNX, __QNX__, ...?) the system as printed out
when configure starts should be enough to work on.

That's an annoyance, but we can easily rename it to zhalloc().
