It's perfectly fair, and at the same time you are absolutely correct to
describe \c as non-portable too. The correct approach is either to test and
adapt, or arrange your s**t so it doesn't NEED an echo without a newline.
Strings can be concatenated before they are printed, it's not rocket science.

I was making a probably unfair overgeneralization. But in any case, the Bourne
shell does not have "echo -n", and when you say, "/bin/sh" you should treat
what you get as if it is the Bourne shell. If you don't want to write a Bourne
shell script, don't start it with #! /bin/sh.

...or as it actually is in this case, start your script with #! /bin/sh but
then ignore it and invoke /bin/sh (as $(SHELL)) directly in your Makefile,
which is what allows CONFIG_SHELL to do the trick.

Fair enough. (I might've guessed that would come up.)


ok
bear.
