From dff7391bd829eb73ad28b6f03a3310daad5605cc Mon Sep 17 00:00:00 2001 From: Haru Date: Tue, 19 Apr 2016 00:34:59 +0200 Subject: Added --enable-Werror option to the configure script It's not always possible (if at all) to pass -Werror in the CFLAGS, since autoconf often generates test-code that produces warnings.
