        (obstack_free): Use it instead of comparing pointers directly,

+       obstack: check def before use; use ({...}) in last Sun C
        * lib/obstack.in.h (__attribute_noreturn__, __extension__):
        Be more careful about checking whether a macro is defined before
        using it, as some compilers complain otherwise.
+       Use statement expressions and __extension__ in
+       Oracle Developer Studio 12.6, where __SUNPRO_C == 0x5150.
        Simplify the logic for __extension__.
