System: NetBSD road-runner.mit.edu 1.3E NetBSD 1.3E (ROAD-RUNNER) #93: Sun Mar 8 00:08:12 EST 1998 nathanw@road-runner.mit.edu:/u1/usr/src/sys/arch/i386/compile/ROAD-RUNNER i386


>Description:
	The Makefile in domestic/lib/libntp uses a .PATH target to find 
sources from lib/libntp. However, it does so in a way that causes make to 
also find the compiled objects from that directory if lib/libntp is built 
first (as in a normal "make build" sequence), so the authdes.c file in 
domestic/lib/libntp isn't compiled - defeating the entire purpose of having
domestic/lib/libntp. 

>How-To-Repeat:
	Run "make build" and notice that nothing is compiled when it 
reaches domestic/lib/libntp. 

>Fix:
	Prevent make from seeing the non-source files in lib/libntp. One 
way is to amke the .PATH target more specific, as in the patch below to
domestic/lib/libntp/Makefile. This is the same trick used by 
domestic/lib/libtelnet, the other domestic lib that shares sources with the
exportable version.
