info auto-import on linking

           Summary: info auto-import on linking
           Product: Xerces-C++
           Version: 2.4.0
          Platform: PC

Hi,
I build (gcc version 3.3.1 (cygming special)) the xerces lib (xerces-c-src2_4_0)
with cygwin (DLL version: 1.5.5) in my w2k (Windows 2000 Professional Ver 5.0
Build 2195 Service Pack 4) and finish with 6 files in libs dir
(cygxerces-c24.dll, libxerces-c24.def, libxerces-c24.map libxerces-c.dll.a,
libxerces-c24.dll.a, libxerces-c2_4_0.dll.a). When I go to samples dir and try
to build the samples, no errors occur but I receive a lot of "infos" from linker...

I found that this "info" are for static attribs. In documentation of ld exists a
topic about auto-import that says using __declspec(dllimport) in header files
when linking eliminate this problem. 
After look in xerces/src/util/compilers/GCCDefs.hpp I found to empty "defines":
    #define PLATFORM_EXPORT
    #define PLATFORM_IMPORT
I try set than to:
    #define PLATFORM_EXPORT     __declspec(dllexport)
    #define PLATFORM_IMPORT     __declspec(dllimport)
and rebuild the library. The result libs decrese in size but when I try to build
some sample I receive a lot of errors about undefined class references.
I found a lot of classes that do not have "*_EXPORT" in headers, classes like
XMLRegisterCleanup in XMLRegisterCleanup.hpp, XMLDOMMsg in XMLDPMMsg.hpp...
I do not know if this is a error, I am only reporting to help.

thanks and please forgive my bad english.
