What is the difference between xerces-c_3_1.dll and xerces-c_3_1D.dll in apache xerces pre-built windows binaries (xerces-c-3.1.1-x86-windows-vc-9.0.zip from http://xerces.apache.org/xerces-c/download.cgi)?
(Similarly there is also xerces-c_3.lib vs xerces-c_3D.lib)
I assume it has to do with different xerces build options, but I can't seem to find any documentation describing the differences.
