From 1f684bcde457d41f2dcb4451df27323924e13b68 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 14 Jul 2017 22:25:58 +0200 Subject: ash: protect WIFSTOPPED use with #if JOBS This change fixes the build in setups where there are no headers defining WIFSTOPPED and WSTOPSIG (where JOBS has to be set to 0). This partially reverts 4700fb5be (ash: make dowait() a bit more readable. Logic is unchanged, 2015-10-09).
