Make bug

[David Tilbrook]

I recently found the following bug (feature?) in System 3, 5, OSx Make
in the following shell script:

cat <<'!' >make.tmp
MAIN:
	echo *
!
make -f make.tmp
make -f - <make.tmp

The outputs on all my systems (4.1, SysV, OSx) in empty directories were:

echo *
make.tmp
echo *
*

Is this an obscure and useful feature the value of which I
fail to understand or appreciate?
