From b9de1157289455b0ca26daff519d4a0ddcd1fa13 Mon Sep 17 00:00:00 2001 From: Dan Albert Date: Wed, 24 Feb 2016 13:48:45 -0800 Subject: Update 4.8.1 to 4.8.3. My previous drop was the wrong version. The platform mingw is currently using 4.8.3, not 4.8.1 (not sure how I got that wrong). From ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.3/gcc-4.8.3.tar.bz2.
