From b67cc8a561756767e1934259c04be8a73a7528d8 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Tue, 3 Jul 2018 11:31:15 +0100 Subject: [PATCH] build: disable pointer to int warnings for 32-bit Converting a 32-bit pointer to a 64-bit integer is generally safe, but generates a lot of warnings when compiling 32-bit code with meson. The warnings are not flagged when using make, so just disable them for 32-bit meson builds.
