To be able to give a more precise answer, I rechecked. Apparently, the
bug is a combined bug of make and sed. Make changed the way line-breaks
in continued shell commands are handled. As a result, the argument for
sed is not formatted as expected by sed. Thus sed throws the error.

(I can only guess that instead of replacing "\\n" with a whitespace the
"\n" is preserved - but that is only a guess.)

One fix is to remove the line-breaks in the command string -> multiple
- -e arguments. Another is to use '"' instead of ''' to embrace the
command string.  This, however, has the consequence that Make-variables
inside the command string are no longer evaluated.

Greetings, Ron.
