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

>This works for me: I see

    echo \\\foobar
    \\\foobar


OUCH!  I was using Cygwin echo, unknown to me (echo is not a executable in Windows, so the windows shell found the Cygwin echo, later in the path, and did not do the built in Windows echo).  

So now I see this:

Cygwin echo from Cygwin shell:

$echo \\\foobar
\foobar

From windows shell:

C:\Temp>c:\tools\cygwin\bin\echo \\\foobar
\\\foobar


And from within GNU make

SHELL=cmd.exe 

foobar:
		echo \\\foobar

C:\Temp>make foobar
echo \\\foobar
\\foobar


I can kind of understand the first two behaviours:  the first, Cygwin echo within a Unix-like shell, tries to behave like Unix.  Second, within Windows, tries to be compatible with windows echo.  

But third, I still don't understand.
