The above is a shell script.

This will generate a bunch of instances of the shell script in the
makefile and make will try to read them as make commands; they aren't
legal make commands.

You have to put the foreach into a script context (precede it with a TAB
in a rule context).

Sure, because warning doesn't evaluate to anything (it just prints
things), so there's nothing for make to read in and thus no syntax
error.
