From 2aefc4ee703ce3ff70ad25915005cacfbaae0c49 Mon Sep 17 00:00:00 2001 From: Bernd Kuhls Date: Fri, 27 Mar 2020 21:23:53 +0100 Subject: [PATCH] gcc: define _REENTRANT for OpenRISC when -pthread is passed The detection of pthread support fails on OpenRISC unless _REENTRANT is defined. Added the CPP_SPEC definition to correct this.
