   * aclocal.m4 (gcc_AC_NEED_DECLARATION): This macro now requires
       INCLUDES to search and does not provide any of its own.  Also it
       now accepts optional ACTION-IF-NEEDED and ACTION-IF-NOT-NEEDED
       parameters.  Also it does not call AC_DEFINE.
       (gcc_AC_NEED_DECLARATIONS): Likewise.  Also this macro now calls
       AC_DEFINE and provides for automatic entries for autoheader.
       (gcc_AC_FUNC_PRINTF_PTR): Cleanup C code in test.

       * configure.in (gcc_AC_NEED_DECLARATIONS): Save and restore CFLAGS
       so we can pass -I flags and include gansidecl.h/system.h in this
       test.

       * acconfig.h: Delete all NEED_DECLARATION_* entries.
