macOS builder fails with sed: 13: @sed.in.11268: extra characters at the end of h command in configure step. Could somebody with a Mac please debug the problem?

macOS builder fails with sed: 13: @sed.in.11268: extra characters at the end of h command in configure step. Could somebody with a Mac please debug the problem?

macOS uses a BSD-based version of sed and apparently an old version at that. There are a number of documented differences among the various versions and I think you are running into one by trying to do the multi-line append here:

		echo "/Definitions added by makesetup/a$NL$NL$DEFS" >>$sedf
		cat $sedf

Searching the web, there are various ways suggested to do this in a manner that will work with all versions. One simple way that seemed to work with both the macOS and GNU versions is to write the contents of $DEFS to another temp file and then use the sed r command instead of a to insert them.

Thanks @ned-deily! sed r command works like a charm.

The PR was an experiment. I'll open a proper PR when everything is in place.
