I think your problem is with the Xerces-C++ build. First of all,
you don't need any of the preprocessor defines -- the build system
will determine which ones are required automatically (and by defining
those that are not required, you can actually end up with a broken
build).

Secondly, I suggest that you start with a static library since it
appears that MinGW has problems with DLL building more often than
not. If that works, you can try to build a DLL and see how it goes.
So to build libxerces-c.lib, do the following (you don't need to
set XERCESROOT anymore):

$ ./configure --disable-shared LDFLAGS=-no-undefined 
$ make

Let me know if this doesn't help.
