Would this also work for other versions of Darwin? Or am I going to have
to set up different OS files for different releases? Are there any
experts out there?

That is a change you can make in Local/Makefile. No need to modify the
OS file.

Surprise, surprise, the structure for ipoptblock is usually defined in
/usr/include/netinet/ip_var.h.

You can cut out all the IP options processing by setting

#define NO_IP_OPTIONS

in OS/os.h-Darwin. This loses you the check for IP option settings
(which should not occur), but some OS do this automatically for you. I
don't know if that is true of Darwin.

Always welcome. Though a straight patch may not make sense unless it
also works on other versions of Darwin.
