/* This header provides a declaritive way of describing the types that
   are used when declaring builtin functions.

   Before including this header, you must define the following macros:

   DEF_PRIMITIVE_TYPE (ENUM, TYPE)

     The ENUM is an identifier indicating which type is being defined.
     TYPE is an expression for a `tree' that represents the type.

   DEF_FUNCTION_TYPE_0 (ENUM, RETURN)
   DEF_FUNCTION_TYPE_1 (ENUM, RETURN, ARG1)
   DEF_FUNCTION_TYPE_2 (ENUM, RETURN, ARG1, ARG2)
   DEF_FUNCTION_TYPE_3 (ENUM, RETURN, ARG1, ARG2, ARG3)
   DEF_FUNCTION_TYPE_4 (ENUM, RETURN, ARG1, ARG2, ARG3, ARG4)

     These macros describe function types.  ENUM is as above.  The
     RETURN type is one of the enumerals already defined.  ARG1, ARG2,
     and ARG3 give the types of the arguments, similarly.

   DEF_FUNCTION_TYPE_VAR_0 (ENUM, RETURN)
   DEF_FUNCTION_TYPE_VAR_1 (ENUM, RETURN, ARG1)
   DEF_FUNCTION_TYPE_VAR_2 (ENUM, RETURN, ARG1, ARG2)
   DEF_FUNCTION_TYPE_VAR_3 (ENUM, RETURN, ARG1, ARG2, ARG3)

     Similar, but for function types that take variable arguments.
     For example:

       DEF_FUNCTION_TYPE_1 (BT_INT_DOUBLE, BT_INT, BT_DOUBLE)

     describes the type `int ()(double)', using the enumeral
     BT_INT_DOUBLE, whereas:

       DEF_FUNCTION_TYPE_VAR_1 (BT_INT_DOUBLE_VAR, BT_INT, BT_DOUBLE)

     describes the type `int ()(double, ...)'.
 
  DEF_POINTER_TYPE (ENUM, TYPE)

    This macro describes a pointer type.  ENUM is as above; TYPE is
    the type pointed to.  */
