Hi,
I am trying to compile xalan c++ 1.10 under mingw using g++, xerces2.8.0 and icu3.2.1. xerces 2.8.0 and ICU3.2.1 dlls are ready but when compiling xalan c++, with the following commands: 
 >cd $XALANCROOT
>runConfigure -p cygwin -c i386-mingw32-gcc -x i386-mingw32-g++ -C --host=i386-pc-cygwin -m icu -t icu 
 >make clean; make

I get the following error:

Thanks for you help
You'll have much better luck getting the head of the Subversion repository to compile cleanly on mingw.
If you really want to try with Xalan-C 1.10, the fix for this error is to modify src/xalanc/Include/PlatformDefinitions.hpp as follows: 

    #if defined(XALAN_USE_NATIVE_WCHAR_T)
    typedef wchar_t                     XalanDOMChar;
    #else
    // UTF-16 character...
    typedef unsigned short      XalanDOMChar;
    #endif

becomes:

    typedef XMLCh  XalanDOMChar;
