The following patch corrects some function attributes. (#61780)

        * glib/ghash.h (g_int_equal, g_int_hash): These are not const.

        * glib/glibintl.h (_glib_gettext): Add G_GNUC_FORMAT(1).

        * glib/gmacros.h: Use reserved symbols in function attribute macros.

        The following patch avoids manual printf()-format parsing
        if a C99-conforming vsnprintf() is available. (#55106)

        * acinclude.m4 (AC_FUNC_VSNPRINTF_C99): New macro to test for a
        C99 conforming vsnprintf.

        * configure.in: Use AC_FUNC_VSNPRINTF_C99.

        * glib/gmessages.c (g_printf_string_upper_bound): Use C99 vsnprintf().
