Yes, although I should stop admitting stuff like that because it shows
my age (but also my good memory retention) :-)

It was to provide compatibility for targets called "include".
I.e. if it has a : it is probably a dependency line not an include
directive.

Best,

$ touch bar.h
$ cat << EOF > m2
include foo.h: bar.h
	@echo out[$@] in[$>]
EOF
$ make -f m2
out[include] in[bar.h]
$ gmake -f m2
m2:2: foo.h:: No such file or directory
m2:3: *** recipe commences before first target.  Stop.

I guess it can be removed :-)
