  C11 requires tv_nsec to be type long, which means that if we change
  it to be a new snseconds_t type in Issue 8, we would have to require
  that snseconds_t is defined as long in order not to conflict with C11.

  This is just a linux kernel bug which needs to be fixed. They have a
  number of other such bugs in x32 too. It's possible to work around it
  in userspace on the library side (we do this in musl libc) but it's a
  bit costly/painful and glibc does not do so yet. There's an open bug
  for it which I filed:

and I don't see any other responses in that discussion.
