The following appeared in gcc head:
commit 3a873c0a7bc8183de95a6103b507101a25eed413

 Rename double_u with __double_u to avoid pulluting the namespace.
 
 gcc/ChangeLog:
 
 * config/i386/emmintrin.h (__double_u): Rename from double_u.
 (_mm_load_sd): Replace double_u with __double_u.
 (_mm_store_sd): Ditto.
 (_mm_loadh_pd): Ditto.
 (_mm_loadl_pd): Ditto.
 * config/i386/xmmintrin.h (__float_u): Rename from float_u.
 (_mm_load_ss): Ditto.
 (_mm_store_ss): Ditto.
This pollution avoidance achieves a direct hit with our /usr/include/math.h:
union __double_u {
 unsigned char __dummy[sizeof(double)];
 double __val;
};
What should we do?
Cheers,
Patrick
