+Subject: [PATCH] src/Makefile: disable -Werror
+
+gcc 8.x has enabled additional warnings that break the build due to
+-Werror, so let's drop -Werror for now. A set of patches has been
+submitted upstream (https://github.com/wolfcw/libfaketime/pull/161) to
+properly fix the gcc 8.x issues, but in the mean time, disabling
+-Werror is a simpler option.
