Subject: 2007-03-15  Jeff Johnston  <jjohnstn@redhat.com>

        * configure.in: Add new --enable-newlib-reent-small option.
        * configure: Regenerated.
        * acconfig.h: Add _WANT_REENT_SMALL.
        * newlib.hin: Regenerated minus PACKAGE macros to add
        _WANT_REENT_SMALL macro.
        * libc/include/sys/config.h[_WANT_REENT_SMALL]: Set _REENT_SMALL
        if not already set.
        * libc/stdio/fflush.c[_REENT_SMALL]: Return immediately if
        there is no buffer.
        * libc/stdio/local.h[_REENT_SMALL]: Fix CHECK_INIT macro to
        use reentrant pointer passed in when resetting the file
        pointer to one of the std streams.
