This is correct, right?

I agree, this seems wrong. I would expect make, after deciding to throw
out that circular dependency, to decide it doesn't know how to build
asdf.ppm and give output like this:
make: Circular asdf.bmp <- asdf.ppm dependency dropped.
make: *** No rule to make target `asdf.ppm'. Stop.
rather than failing with an incorrect value. I'll look into this.

This is correct, right?

As far as I can tell, make works all the time when it should work. What
is broken is that in some situations where make can't do what you want,
it will try to do something bogus instead of just printing an error.
Am I correct here, or am I missing something?
