[wplug] Very strange problem

[Hagbard Celine]

A question for the hackers here:

I'm attempting to learn something about network programming, and to that end,
I've begun playing with ping and traceroute.  While doing this, I've
encountered something that totally baffles me...

When I include <netinet/ip.h>, certain of the defines and declarations are
skipped, even though they *should* be done.  If, however, I change the path -
perhaps to <netinet/ipA.h>, or even "ip.h", everything works just fine and
dandy.  Why should the path to the header make a difference in what is parsed?

Before you ask which distro I'm using, I'm not;  I roll my own system...  Also,
this started about two weeks ago.  Could I have done something to myself?

Thanks much,
Hagbard
