Problem with -include target in make-3.81(bug?)

[Lee]

make-3.81 behaves differently from the previous versions, backward incompatible.

Is this a bug or a fix?

 

$ cat makefile
# -include target => version 3.81 fails to issue an Error => bug?

all:; @exit 0
-include done
done:; @echo $(MAKE_VERSION); exit 1

$ for f in make-3.79.1 make-3.80 make-3.81b1 make-3.81; do
> echo [ $f ]
> ~/bin/$f      
> done

[ make-3.79.1 ]
3.79.1
make-3.79.1: *** [done] Error 1
[ make-3.80 ]
3.80
make-3.80: *** [done] Error 1
[ make-3.81b1 ]
3.81beta1
make-3.81b1: *** [done] Error 1
[ make-3.81 ]
3.81

(no Error in 3.81)
