Binaries for GIF output is available at
http://128.101.73.80/projects/mapserver/ms33gif.zip.  Binaries for PNG
output is available at http://128.101.73.80/projects/mapserver/ms33png.zip.
The PNG version requires zlib.dll which needs to be located somewhere in the
system path.  The safest place to put it is in \winnt\system32 directory.

If anybody is interested in qualitative performance comparisons between the
two outputs, check http://128.101.73.80/projects/ms_demo (for GIF output)
and http://128.101.73.80/projects2/ms_demo (for PNG output).  I don't seem
to notice much difference.  For huge datasets, try
http://128.101.73.80/projects/minnesota and
http://128.101.73.80/projects2/minnesota.

For numbers, PNG output (10-15K output sizes) with vector data is about 2-4K
more than the GIF output (14-18K output sizes).  With raster data, GIF
output (192K) is about 30K more than PNG output (162K).  I don't really have
time to set up a more formal comparison but perhaps someone who downloads
the binaries can do it.  It'll be interesting to see how NT compares with
UNIX as well.

Specs:  the system has dual 400Mhz P-II processors, 16Gb RAID level 5
storage (80% full), 256Mb ECC RAM,  WinNT 4.0 sp6, IIS 4, MapServer 3.3.010
