icp greyscale conversion to jpeg broken

[warmerdam@…]

Using the cygwin executables posted Dec 5th or 6th.  I am using the supplied
Cygwin dll, but my cygwin environment (not sure if this matters) reports:

warmerda% uname -a
CYGWIN_NT-5.1 GDAL800XP 1.3.3(0.46/3/2) 2001-09-12 23:54 i686 unknown

The command:

icp.exe jpeg small.tif small.jpg

Seems to complete fine, but image_info.exe reports the following:

N:\wrk\ossim>image_info.exe -i small.jpg
theDefaultElevationPath:
Corrupt JPEG data: 1 extraneous bytes before marker 0xc0

Viewing the image, it has some significant anomolies.  The results were
substantially worse on a larger original.  I just made this image small to
work with easily.

I would guess that the output jpeg file was opened in text mode instead of
binary mode but I am not at all sure of that.  I am not even sure if that
can occur with Cygwin builds.
