From 86e5eb4f58a276870fbd29e3711b36e4a4280979 Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Sun, 24 Jul 2022 09:21:57 +1200 Subject: Remove dead getrusage replacement code. getrusage() is in SUSv2 and all targeted Unix systems have it. Note that POSIX only covers ru_utime and ru_stime and we rely on many more fields without any kind of configure probe, but that predates this commit. The only supported system we need replacement code for now is Windows, and that can be done without a configure probe.
