Frank, thanks (again) for your help.  I'm in business.  I stepped into
the code and found that WMS support was being built in (after I
installed curl and changed the nmake.opt file).  For some reason,
though, WMS doesn't show up on gdalinfo --formats.  The reason my open
was failing was because I had three bytes of white space before my
<GDAL_WMS> tag that were invisible in my text editor.
