opt_netgraph in netgraph/netgraph.h?

The problem isn't that there is no generated opt_netgraph.h but that of all 
the numerous opt_netgraph.h files, none are found during the KLD compilation. 
I suspect either:

	1. I mistakenly deleted or lost to fs corruption the key opt_netgraph.h
	2. A /usr/src/* Makefile or a bsd include mk is missing a -I path specifier
	3. Whomever submitted the last netgraph.h edit forgot to tweak a conf or 
	4. some part of a recent cvsup failed and I didn't notice it

Reason (1) is not likely since a kernel rebuild should have restored any such 
deleted file...

My current workaround is to just touch an opt_netgraph.h into the "@" 
symlinked directory. Works fine. I just remain curious as to what's really
