+Subject: [PATCH] Fix nasty parallel build problem reported by Gentoo and
+ Westermo
+
+Independently of each other both the Gentoo project and Westermo found
+an issue with massively parallel builds on monster-core-machines. At
+Westermo there are 40 core Xeon monsters that stumble when building
+sysklogd.
+
+The Gentoo bug report is here:
+
+ https://bugs.gentoo.org/701894
+
+The problem stems from strlcat.c and strlcpy.c being used for both
+the libcompat convenience library built for libsyslog and als for
+syslogd when the system does not have either of the APIs in libc,
+i.e. most Linux systems with GLIBC or musl libc.
+
+I can either rewrite the Makefile.am files to handle dependencies
+better, or we just disable parallel build like this patch. There's
+too few source files to gain anything from parallel build anyway.
