Most make programs do this.  The reason for this behavior is the for
loop.  When make sees the for loop it executes a shell.  The shell does no
return-code checking whatsoever.

To fix the problem, try the following:

	for ii in $(DIRS); do cd $$ii; if ! make all; then exit 1; fi; done

Please note that the brackets "()" will spawn another subshell.
