Mark,

I think you would pretty much have to recompile everything with compatible
build options.  I could provide mapserv with this already but I don't know
how to build the PHP stuff.

Recent innovations in building mechanisms on windows (to use DLL interfaces
more cleanly for OGR) should help resolve the problem of over-tight linkage
between MapServer and OGR by 4.4 release time.
