The commits are:
http://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=e3a1f6b50495473f677f413d8740808a3fde5a9a

I think doing special casing for x32 as indicated in the previous mail
could solve the problem also for that architecture.
Add/modify gcc/ada/{s-linux-x32.ads,s-osprim-x32.ads} according to:
type tv_nsec_t is private;
type tv_nsec_t is new Long_Long_Integer;
type timespec is record
tv_sec : time_t;
tv_nsec : tv_nsec_t;
end record;
pragma Convention (C, timespec);
