Are you sure about this? Last week when you asked about adding -k I
wondered about make's return status and looked the documentation, I
didn't find an answer, but I assumed it would do the logical thing,
which is if any command returns non-zero the final exit status is
non-zero.

To test this I created the following Makefile:

all: one two

one:
	sh -c "exit 1"

two:
	sh -c "exit 0"


then I tried a make -k, for instance:

$ make -k; echo $?
sh -c "exit 1"
make: *** [one] Error 1
sh -c "exit 0"
make: Target `all' not remade because of errors.
2

Note, you get the non-zero exit status even if the last command
succeeded. Try various combinations of exit values for targets one and
two and you'll see it always does the right thing.

Granted, this is with GNU make, but I would expect other makes to have
the same behavior. Are you seeing something different?
