You might have to specify the CDECL calling convention.

 From the documentation for define_c_func():

    "On Windows, you can add a '+' character as a prefix to the 
     function name. This indicates to Euphoria that the function 
     uses the cdecl calling convention. By default, Euphoria assumes 
     that C routines accept the stdcall convention."

i.e.

    entry = define_c_func (dll, "+dll_entry_", {C_UINT}, C_UINT)
