Yes I could change the time stamp of a directory on Win 2K.

On Win 98 when I tested it I could not change the timestamp of a directory.
The touch.exe from the fil40b.zip on Simtel gives an EACCESS error. The
touch.exe that i built using the CVS LIBC and the attached patch file also
gives the same EACCESS error on Win 98 and Win 2K. The patch file from
yesterday does not fail on Win 2K.

Should setting time on a directory fail? If it should not fail then should I
put this on my list of items to come back to.

To save time again i have attached an updated utime.c patch that fails when
trying to set the time on a directory as occurs with the exisiting code on
Win 9x. AS I see it it is better to have them consistent than different.
