[fdo-internals] FDO 3.3 compatible MrSID and ECW Plugins

Hi Frank,

When you build a dll, the embedded manifest in the dll contains the version number of the dependent dlls. Since VS 2005 and VS 2005 SP1 uses different versions of the crt libraries, the version number in the embedded manifest would be different.
So if someone tries to run an application built with SP1 and SP1 crt is not installed on the machine,  the application fails to load.

I am not sure why depends.exe would not show any problems. However, the problem is not missing entry points since all the entry point should be ok.

Can you explain the implications of building with VS 2005 instead of VS 2005
SP1?  Why does it matter?  Why would depends.exe not report missing entry
