infinite echoing of kernel version caused by echo

[Eckhart Guthöhrlein]

Hi all,

please have a look at the simple Makefile below. On several machines
running Debian unstable, it outputs the running kernel's version
endlessly. If I enclose "endless" in double quotes, it works as
expected. This does not happen when using echo on the command prompt, so
it has to be related to make somehow.
Is this a bug? Has anybody observed this behavior and found the reason
or a workaround?

Thanks for any help,
Eckhart


Here is the Makefile:

default:
        echo endless
