RE: why does command echo \\\foobar print \\foobar

I see.  OK, thank you, but right now, I actually settled on using perl for what I needed this for.  So it does not matter, I just need to make sure perl gets precisely 2 backslashes:  "\\foobar" (I suppose I could process this in perl if it gets a different numbers, it's just that, until I see documented or reasonably explained behavior, I don't know what I will be getting in Perl 5 years from now, with the new version of GNU make).

If you want to make sure CMD's built-in "echo" is colled, not some "echo.exe", then put a dot on the command.

    echo foo
will find a .exe named echo if it can

    echo. foo
will never find a .exe, so fallsback to the cmd.exe built-in

The same "append a dot" trick works for all CMD.EXE built-in functions: mkdir, rmdir, dir, type, etc
