    Update GLIB_CHECK_COMPILE_WARNINGS macro to work with Autoconf 2.64
    
    Quoting its NEWS file: "The m4sh macros AS_IF and AS_CASE can now be
    used in shell lists.  The responsibility for supplying a trailing
    newline now belongs to the call site, but since most users did not add
    dnl, this generally results in fewer empty lines in configure."
