I think you mean ECHO_MSG here. :)
ECHO_MSG is used to output an informational message to a terminal,
while ECHO_CMD is used to output a string to a file or through a pipe.
The difference between them is that ECHO_MSG can be disabled by
setting it to a null command (true) for automated building, while
ECHO_CMD may not be disabled because it is essential to be functional
in order to output given strings properly.
The problem I fixed is that ECHO was used where it should be ECHO_CMD
- as explained in the commit log, ECHO can be set to a null command
when make(1) is invoked with the -s option.

That's an idea. They are almost equivalent except the # character, as
'make -s' suppresses the output. :)
