[Shapelib] Including shapelib.dll in Visual C++ 2008 Express project

[Sanak]

Hi Raphael,

It seems that the original Visual C++ shapelib project preprocessor
definitions are invalid. (generated shapelib.lib and shapelib.dll symbols
are incompatible)

Please try as follows,
1. modify shapelib project C/C++ preprocessor definition from VC property
page
   SHPAPI_CALL=__stdcall
     --> SHAPELIB_DLLEXPORT
2. modify each source files(dbfopen.c/shpopen.c/shptree.c) C/C++
preprocessor definition from VC property page
  SHAPELIB_EXPORTS;SHPAPI_CALL=__stdcall;$(NoInherit)
     --> SHAPELIB_DLLEXPORT
3. rebuild shapelib project.
4. import generated shapelib.lib to your project and build.

Regards,

Sanak.
