What is happening is that `make depend' invokes a script which finds
#includes in the source code, and builds a make dependency. However,
it's not very intelligent, and doesn't ignore:

#ifdef INET
#include <stuff>

when INET isn't defined. :-) This bites on several C files.
You just have to hand-prune the Makefile after make depend :-)
This is 2.9BSD, BTW, ignore if you're not using it.
