>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
