>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
