From ad0241d2a412907f181750525427f717a6f0b239 Mon Sep 17 00:00:00 2001 From: Daniel Stone Date: Sat, 18 Jun 2016 16:04:30 +1000 Subject: [PATCH] Build: Silence shift-negative-value warning Pixman's headers include a representation of -1 in fixed-point, which is -1 << 16. This trips a GCC warning about shifting negative values. As we can't do much about it, just silence the warning.
