[mapguide-internals] GDAL Provider update

Hmm... Now this is interesting.
I was digging around the GDAL project website and found a link to some updated GDAL 1.6 binaries. These binaries are compiled with Visual Studio 2008. They also include ECW and SID libraries compiled with Visual Studio 2008.
I used the 32 bit GDAL 1.6 binaries from http://vbkto.dyndns.org/sdk/release-1500-gdal-1-6-mapserver-5-6.zip and dumped them on my Windows 2008 R2 64 bit test machine. They also have 64 bit binaries posted.
The consistent dll set seems to make a "slight" difference. SID, ECW, and JPEG2000 seem to be working with a single user hitting them. I haven't tried a multi-user scenario yet.
Here's the dlls I copied over:

No kidding :)
Did you see the patches attached to this ticket?
found and created a patch for a reference counting issue in the provider,
but I don't think it's ever been applied (I think fixing it at the time may
have caused a problem?)
Also, I'm still not convinced that not guarding the stylization (re
mapguide_raster_stability.patch from Haris) call isn't risky. I didn't
really understand the arguments one way or the other, but it sounded like
this was trading potential stability for performance. I think this would be
around here now:
For the record, I've had success on Windows Server 2003, 32bit, MapGuide
2.1. Haven't tested anything newer, or x64.
