From 6aac70a870fc40482eca943ff0b64003497d69c1 Mon Sep 17 00:00:00 2001 From: Jeff Hostetler Date: Thu, 20 May 2021 18:28:10 +0000 Subject: simple-ipc: correct ifdefs when NO_PTHREADS is defined Simple IPC always requires threads (in addition to various platform-specific IPC support). Fix the ifdefs in the Makefile to define SUPPORTS_SIMPLE_IPC when appropriate. Previously, the Unix version of the code would only verify that Unix domain sockets were available. This problem was reported here: https://lore.kernel.org/git/YKN5lXs4AoK%2FJFTO@coredump.intra.peff.net/T/#m08be8f1942ea8a2c36cfee0e51cdf06489fdeafc Reported-by: Randall S.
