Ah, yes, I've missed that.  What about introducing an additional layer
like this:

  #ifdef FT_CONFIG_OPTION_USE_MODULE_ERRORS
  #define FT_( error )  error
  #else
  #define FT_( error )  FT_Err_ ## error
  #define FT_NOERRORDEF  FT_ERRORDEF
  #endif

  ...

    FT_NOERRORDEF( FT_( Ok ),                               0x00, \
                   "no error" )

    FT_ERRORDEF( FT_( Cannot_Open_Resource ),               0x01, \
                 "cannot open resource" )

    ...


I think this should make it possible to retain backwards
compatibility.
