Bart / Tom,

Actually I am always pretty nervous about dropping in a gdal12.dll
built from a different version of GDAL than what MapServer
was built against.  MapServer uses the OGR C++ API and any
minor change to the C++ API will generally break compatibility.

So you can try, but it if doesn't work you would likely be looking
at a harder re-compilation problem.  Possibly carrying the
VRT driver changes back into a GDAL 1.2.6 tree or bugging DM
for a newer MS4W build.
