System: NetBSD sibyl.chez-dall.org.au 1.3E NetBSD 1.3E (SIBYL) #4: Tue Apr 21 00:41:00 CST 1998 ian@sibyl.chez-dall.org.au:/usr3/netbsd-1.2/lsrc/sys/arch/pc532/compile/SIBYL pc532


>Description:

If there is an implicit make rule which could make a target from a dependant,
that dependant gets added to .ALLSRC and .OODATE even when there is
an explicit rule. This is more aggressive than other makes and can cause
problems.

>How-To-Repeat:


Create a Makefile:

foo.o:	bar.c
	@echo Transforming $? to foo.o

Then:

touch foo.c bar.c.
make

Produces:

Transforming bar.c foo.c to foo.o

Whereas with gnu make:

gmake

Produces:

Transforming bar.c to foo.o

Responsible-Changed-Why:  
There is now a "toolchain-manager" which is the proper default role 
account for handling problem reports in the toolchain category.
