Well OK, please do.  But, is there any chance you can tell me, on Windows, 
using GNU make, and using either Windows echo or Cygwin echo (I can't predict 
which, some people have Cygwin installed some don't and I can't control that, I 
have to support either way),

how do I reliably echo so that it echoes " \\foobar"

by "reliably" I mean, that it is guaranteed to work now and later with future 
revisions of Gnu make?

Obviously, Make removes one of the 3 backslashes, before it invokes

I will try to look into this some day.  But this area is so delicate,
what with all the shells it supports, that I'd hesitate to change
anything unless I see a clear bug.
