From 0d6ee549bc86fd330672a79d9a87d2c3825eea67 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 5 Jul 2010 14:12:22 +0200 Subject: don't make __errno_location / __h_errno_location hidden Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089) __errno_location / __h_errno_location access has to go through the PLT like malloc/free, so the linuxthread variants gets used instead when compiling with -pthread.
