rlim_t: Unsigned integer type used for limit values.
rlim_t is signed on some non-POSIX platforms so the comparison is needed
there. Sorry, don't recall which platforms offhand, but a quick Google
search suggests that older HP-UX is one such (this version was before
the requirement in question was added to POSIX). See page 18 of:

How about compiling with -Wno-tautological-compare instead, at least for
code derived from Gnulib? In my experience, -Wtautological-compare is
more trouble than it's worth, for Gnulib code.
