lispbibl.d:
#elif 0
  /* Usually one would omit the array's limit */
  #define unspecified

The above description/definition looks a bit crooked to me. I mean its
possible to declare an array inside a structure without any size when
compiling it with g++. But this is just ignored by the preprocessor.
And there is an #else block too for other platforms but that above
condition should be fixed.
