* 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.
