+/* Before including this file, you should define a macro:
+
+     DEF_BUILTIN (ENUM, NAME, CLASS, TYPE, LIBTYPE, BOTH_P,
+                  FALLBACK_P, NONANSI_P)
+
+   This macro will be called once for each builtin function.  The
+   ENUM will be of type `enum built_in_function', and will indicate
+   which builtin function is being processed.  The NAME of the builtin
+   function (which will always start with `__builtin_') is a string
+   literal.  The CLASS is of type `enum built_in_class' and indicates
+   what kind of builtin is being processed.
+
+   Some builtins are actually two separate functions.  For example,
+   for `strcmp' there are two builtin functions; `__builtin_strcmp'
+   and `strcmp' itself.  Both behave identically.  Other builtins
+   define only the `__builtin' variant.  If BOTH_P is TRUE, then this
+   builtin has both variants; otherwise, it is has only the first
+   variant.
+
+   TYPE indicates the type of the function.  The symbols correspond to
+   enumerals from builtin-types.def.  If BOTH_P is true, then LIBTYPE
+   is the type of the non-`__builtin_' variant.  Otherwise, LIBTYPE
+   should be ignored.
+
+   If FALLBACK_P is true then, if for some reason, the compiler cannot
+   expand the builtin function directly, it will call the
+   corresponding library function (which does not have the
+   `__builtin_' prefix.
+
+   If NONANSI_P is true, then the non-`__builtin_' variant is not an
+   ANSI/ISO library function, and so we should pretend it does not
+   exist when compiling in ANSI conformant mode.  */
