Illegal handles in FindClose [Resend]

[Dominik Strasser]

The application I am trying to make runnable passes an illegal handle to
FindClose. It is 0xcccccccc which is an unitialized stack address (at
least I remember to have seen those when I was doing Windoze programs).
I wrapped the access into an exception handler.

Alexandre:
Why didn't you apply this patch even after I resent you a diff -u ?
Is there anything wrong with it ?

ChangeLog:
        * files/dos_fs.c
        Dominik Strasser <dominik.strasser at mchp.siemens.de>
        Allow illegal handles in FindClose
