Subject: cc1_main: fix -Wsign-compare on FreeBSD
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1231be927ba509ec8e1a31f9322529748daebf94;p=clang

cc1_main: fix -Wsign-compare on FreeBSD

Its __rlim_t is intentionally signed (__int64_t) because of legacy code
that uses -1 for RLIM_INFINITY.
