Actually, glibc declares ioctl in stropts.h too.  However, stropts.h is
not mention anywhere in the glibc manual.  The glibc manual says the
ioctl function is declared in sys/ioctl.h.  The man page for ioctl on my
system says sys/ioctl.h.

Does the new POSIX document change anything?  I notice that "ioctl.h"
doesn't result in anything on the current opengroup.org site.

I don't care strongly.  Given that opengroup.org uses stropts.h, that
might be nice if we want to support them, but I don't recall hearing of
that header file before so it may be simpler to forget about it.  So a
+0.5 on sys/ioctl.h from me.
