   4  * Get information about what IDL features the IDL compiler has, similarly to
   5  * the "version" standard header in C++.
   6  *
   7  * In C++ it can be used like this if you want to be compatible with older
   8  * versions of TAO:
   9  *
  10  * #include "tao/orbconf.h"
  11  * #if defined TAO_HAS_IDL_FEATURES && TAO_HAS_IDL_FEATURES
  12  * // Use this macro if you are using something that's not the max possible
  13  * // version.
  14  * #  define TAO_IDL_IDL_VERSION 0x30000
  15  * #  include "tao/idl_features.h"
  16  * #  if defined TAO_IDL_HAS_FEATURE && TAO_IDL_HAS_FEATURE
  17  * #    define USE_FEATURE
  18  * #  endif
  19  * #endif
  20  *
  21  * In IDL it can be used like this if you want to be compatible with older
  22  * versions of TAO:
  23  *
  24  * #if defined __TAO_IDL_FEATURES
  25  * #  include __TAO_IDL_FEATURES
  26  * #  if defined TAO_IDL_HAS_FEATURE && TAO_IDL_HAS_FEATURE
  27  * #    define USE_FEATURE
  28  * #  endif
  29  * #endif
  30  *
  31  * Note that support for annotations and anonymous types in IDL4 predate this
  32  * file, so they are a potential special case depending on what ACE/TAO is
  33  * being used.
