//  DECLSPEC.H:  Define the DLL_BASED and DLL_CLASS manifests for
//               DLL export/import decoration
//
//   This file is based upon the following macro definitions:
//
//        _CFRONT_PASS_     defined in MAKEFILE.DEF for CFRONT preprocessing;
//
//        _cplusplus        defined for all C++ compilation;
//
//        NETUI_DLL         defined in $(UI)\COMMON\SRC\DLLRULES.MK, which is
//                          included by all components which live in NETUI DLLs.
//
//        DLL_BASED_DEFEAT  optional manifest that suppresses __declspec;
//
//  This file generates two definitions:
//
//        DLL_BASED         which indicates that the external function, data item
//                          or class lives in a NETUI DLL; expands to nothing,
//                          "_declspec(dllimport)", or "_declspec(dllexport)"
//                          depending upon the manifest above.
//
//        DLL_CLASS         which expands to "class", "class _declspec(dllimport)",
//                          or "class _declspec(dllexport)" depending on the
//                          manifests above.
//
//        DLL_TEMPLATE      expands to nothing outside of the DLLs; expands to
//                          DLL_BASED inside the DLLs.   In other words, the standard
//                          template is local to the defining link scope.  To
//                          declare a template as "dllimport", another set of
//                          macros exists which allows direct specification of the
//                          desired decoration.
