Problem passing Windows path names from batch file to bash script

[Gary Johnson <garyjohn at spk dot agilent dot com>]

I am trying to pass Windows path names from a Windows batch file to 
a Cygwin bash script.  I have found a solution using Windows 
environment variable substitution to replace \s with /s before 
passing the name to bash, but I cannot figure out how to pass the 
name without that replacement.  The problem is with names of the 
form

    "\\host\user\file with spaces"

No matter what I've tried, bash insists on collapsing the two 
leading \s to one, like this,

    \host\user\file with spaces

before anything else can be done with the name.


Here's an illustration of the problem.  I've created a batch file, 
foo.bat, that contains the following lines:

    @echo off
    echo %1 '%1'
    C:\cygwin\bin\bash -c 'echo %1'
    C:\cygwin\bin\bash bar %1 '%1'

and a file, bar, in the same directory containing these lines:

    echo $1 "$1"
    echo $2 "$2"

Executing the following command from the Command Prompt,

    foo "\\host\user\file with spaces"

produces the following output:

    "\\host\user\file with spaces" '"\\host\user\file with spaces"'
    \host\user\file with spaces
    \host\user\file with spaces \host\user\file with spaces
    "\host\user\file with spaces" "\host\user\file with spaces"


I can come up with a number of reasons why I think the results 
should be different, but that doesn't really matter, since there 
must be something I'm missing.  Would someone please explain this 
behavior or direct me to the fine manual I should have read?  How 
should one pass such a path name from Windows to a bash script 
without losing any information?

Thanks,
Gary
