System: NetBSD zorkmid.mit.edu 1.5W NetBSD 1.5W (ZORKMID-$Revision: 1.12 $) #104: Sun Jun 24 21:48:35 EDT 2001 jhawk@zorkmid.mit.edu:/usr/local/netbsd-current/src/sys/arch/i386/compile/ZORKMID i386


>Description:
Setting "RES_OPTIONS=debug" does not work for resolver debugging.

This appears to be because, despite the fact that libresolv is built
with -DDEBUG to get this support, res_init.o, which is part of libc,
is not so-built.
>How-To-Repeat:
"env RES_OPTIONS=debug ping and.mit.edu" and watch it fail.

>Fix:
Build res_init.o with -DDEBUG. I'm not sure of the best way, though.
Setting CPPFLAGS+=-DEDBUG in src/lib/libc/Makefile would certainly do
it, but that would build other things with -DDEBUG and that is probably
undesirable.

Conversly, changing the #ifdef DEBUG to #ifdef RES_DEBUG in res_init.c
would probably complicate merging.

Perhaps setting -DRES_DEBUG in the Makefile and then adding

	#ifdef RES_DEBUG
	#define DEBUG
	#endif

at the head of res_init.c?

Thoughts?
