        * aclocal.m4 (GCC_NEED_DECLARATION): Modify macro to accept a
        shell variable argument instead of only hard coded functions.
        (GCC_NEED_DECLARATIONS): New macro to accept multiple functions.
        * configure.in: Collapse multiple calls to AC_CHECK_FUNCS into one
        call.  Collapse multiple calls to GCC_NEED_DECLARATION into one
        call to GCC_NEED_DECLARATIONS (new macro.)  Check if we need
        declarations for bcopy, bcmp and bzero.
        * acconfig.h: Add stubs for bcopy, bcmp and bzero declarations.
        * gansidecl.h: If we have bcopy but don't declare it, then do so.
        Likewise for bcmp and bzero.  Only define macros for bcopy, bcmp,
        bzero, index and rindex if they aren't already present.
