BTW: Is the $$var gmake specific?

No. $ is a (special?) make variable that contains only a dollar sign. To
expand the variable in the Makefile, you have to write $$ (like for any
other Makefile variable whose name has only a single character, like $@,
$<, etc). As a result, you get a single dollar sign in the shell command
text. :-)

I guess I need this in my personal tree:

diff --git a/Michael b/Michael
index 5318944..2ff6a75 100644
--- a/Michael
+++ b/Michael

@@ -0815,2 +0815,2 @@ endif

-stupid remark about lower case
-stupid question about escaping $
+compensate for lack of morning coffee
+note that an empty shell var is more than nothing at all
