Yes.  The Solaris-like definition has its point.  Using sysconf or
getpagesize in the macro is fine.

Aren't these BSD based?  However, when I introduced SIOCGIFADDR and
friends back in 1998, I didn't look anywhere besides the already existing
definitions for SIOCGIFCONF and SIOCGIFFLAGS in Cygwin's asm/socket.h.
I've just used the next values in the row and they were accepted that
way by Geoff.

Don't bother.  Is it a value which could be changed in Cygwin or Winsock?

What are you trying to implement?  I'm really curious.
