            Bug ID: 27252
           Summary: nm doesn't recognize null device on MS-Windows
           Product: binutils
           Version: 2.36

Patch to recognize the null device on MS-Windows

On Unix, if you type "nm -B /dev/null", you get a nice warning:

       nm: Warning: '/dev/null' is not an ordinary file

But on Windows no such warning happens, and 'nm' behaves as if the null device
were a regular file of zero size.  This is because the MS-Windows
implementation of 'stat' doesn't report the null device as a character-special
file, it reports it as a regular file.

The attached file fixes this problem, and a similar problem in 'elfedit'.
