This:

#define HvMROMETA(hv)   (SvOOK(hv) \
                        ? (HvAUX(hv)->xhv_mro_meta ?
HvAUX(hv)->xhv_mro_meta : \
mro_meta_init(hv)) \
                        : NULL)


makes the Cray XT4 cc extremely unhappy (= does not compile) since
HvMROMETA(hv) is then used for example like this:

HvMROMETA(stash)->cache_gen

That is, gleefully deferencing the HvMROMETA() even though it can be NULL.
