Just for the record, Linux is the only OS I've tried to run on where
this is needed. I did the compatability hacks in pc.h a couple years
ago, with the help of one of my cow-orkers, who was running Slackware.

What about the other defines in the original code (for ICMP, etc.)? It
seems like glibc 2 systems still need them.

So it's:
#if defined(__linux__) && defined(__GLIBC__) && !defined(__FAVOR_BSD)
/* defines go in here */
#endif
Is that right? What happens on a non-Linux system running glibc? (Or
is this not a case that's likely to occur?)
Thanks, all!
