I guess the OpenBSD community hasn't been using PLIB recently so the
code has 'rotted'...if you have a fix, please contribute it - but there
are not (AFAIK) any other OpenBSD users here who could hope to solve
your problem.  Maybe some NetBSD or FreeBSD people here can help?

Under Linux, the 'ioctl' call has an optional third argument:

      #include <sys/ioctl.h>

      int ioctl(int d, int request, ...)

I think (from the sound of the error), that OpenBSD has somehow defined 'ioctl'
as a macro - that's **WRONG** because in C++ you should be able to overload
the names of system functions (as we have done here) - but if the host OS
defines them as macro's, that won't work.

I guess you should demand that OpenBSD fix this - but since that's unlikely
to have the immediate effect you need, I guess the best fix is to replace
all of *our* overloaded ioctl functions with something like XXXioctl - so
they don't trigger the macro substitution.

Can you confirm that this *truly* is the cause - and if it is, one of us
will fix it for you.

Yuk, Yuk, Yuk!
