-/* In a.out systems, we need to have these dummy constructor and destructor
-   lists in the library.
-
-   When using `collect', the first link will resolve __CTOR_LIST__
-   and __DTOR_LIST__ to these symbols.  We will then run "nm" on the
-   result, build the correct __CTOR_LIST__ and __DTOR_LIST__, and relink.
-   Since we don't do the second link if no constructors existed, these
-   dummies must be fully functional empty lists.
-
-   When using `gnu ld', these symbols will be used if there are no
-   constructors.  If there are constructors, the N_SETV symbol defined
-   by the linker from the N_SETT's in input files will define __CTOR_LIST__
-   and __DTOR_LIST__ rather than its being allocated as common storage
-   by the definitions below.
-
-   When using a linker that supports constructor and destructor segments,
-   these definitions will not be used, since crtbegin.o and crtend.o
-   (from crtstuff.c) will have already defined __CTOR_LIST__ and
-    __DTOR_LIST__.  The crt*.o files are passed directly to the linker
-   on its command line, by gcc.  */
-
-/* The list needs two elements:  one is ignored (the old count); the
-   second is the terminating zero.  Since both values are zero, this
-   declaration is not initialized, and it becomes `common'.  */
