Re: patch to allow touch to work on HPFS (and others, maybe??)

[Mark Paulus <mark dot paulus at mci dot com>]

I would also like to send this to Andrew DeFaria, since he
seems to have access to a ClearCase volume he was having
problems with.  

Andrew, could you compile and run the program below against
your Clearcase volume, and either return the results to 
cygwin-patches@cygwin.com, or to me, and I'll post them?

Thanks.
