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 olderĀ  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.

Would it be acceptable to add a pragma to turn this warning off at that point? (And explain why, against immediate appearances, it's needed?)
