Thanks! Also for back-patching them.

Regarding the comment,

I personally don't care much about those missing limits on the Hurd, but
Thomas mentioned in
CA+hUKG+tqFVY7Fi=WBvZ6-UsATjcPNBDtphDm7YLjevm2kxSvw(at)mail(dot)gmail(dot)com (and
Samuel Thibault cited the same sentence to me now when I discussed the
commit with him) that POSIX said "A definition of one of the symbolic
constants in the following list shall be omitted from <limits.h> on
specific implementations where the corresponding value is equal to or
greater than the stated minimum, but is unspecified". So "requires at
least 16" might be a bit too strong here, AIUI.

Right, will look into this next.
