Martin,

On my home machine with wxWidgets build as individual static libraries
using expat included with wxWidgets, wx-config --libs xml yields the
following output:

-L/mingw/lib  -mthreads  /mingw/lib/libwx_baseud_xml-2.8.a
/mingw/lib/libwx_baseud-2.8.a -lwxregexud-2.8 -lwxexpatd-2.8 -lz
-lrpcrt4 -luuid -lodbc32 -lole32 -loleaut32 -lwinspool -lwinmm -lshell32
-lcomctl32 -lcomdlg32 -lctl3d32 -ladvapi32 -lwsock32 -lgdi32

It appears that in this case, wx-config is returning the correct expat
library to link against.  I'll check my machine a work tomorrow.  I'm
pretty sure I build wxWidgets using the expat library I build separately
and see if it includes -lexpat instead of -lwxexpatd-2.8.
