The templated function is already placed in .h (bot_globals.h):

namespace Light
{
//extern const mplane_t *lightplane (NULL);
//extern Vector lightspot;
   extern Color g_pointColor;

   template <typename nodeType, typename surfaceType> extern const bool RecursiveLightPoint (const nodeType *const node, const Vector &start, const Vector &end);

   inline const bool IsSoftwareDrawingMode (void)
   {
      static const bool isSoftwareDrawingMode (IS_DEDICATED_SERVER () || GetModuleHandle ("sw.dll") != NULL);

      return isSoftwareDrawingMode;
   }

   inline const bool ActualRecursiveLightPoint (const Vector &start, const Vector &end)
   {
      return IsSoftwareDrawingMode () ?
         RecursiveLightPoint <mnode_t, msurface_t> (sv_worldmodel->nodes, start, end) :
         RecursiveLightPoint <GL_mnode_t, GL_msurface_t> (reinterpret_cast <GL_mnode_t *> (sv_worldmodel->nodes), start, end);
   }

   inline const unsigned char R_LightPoint (const Vector &p)
   {
   // Reliability check.
      if (sv_worldmodel == NULL)
         return 0u;

      if (sv_worldmodel->lightdata == NULL)
         return 255u;

      Vector end (p);

      end.z -= 2048.0f;

      return ActualRecursiveLightPoint (p, end) == false ? 0u : static_cast <unsigned char> (g_pointColor.GetAvg ());
   }
}

I don't understand the hack. Rather I would like to understand somehow the problem (why mingw doesn't see the function) and solve it the way mingw can see it (without workarounds). Can You help again?

[EDIT]
The cygwin file - even if it's compiled - it is not loading on my mandriva 2011 linux test server.
The problem reported by MinGW has to be definitely somehow resolved.
