From 3186be22b6598fbd467b126347d1c7f48ccb7f71 Mon Sep 17 00:00:00 2001 From: Dan Albert Date: Thu, 14 Jan 2016 16:43:34 -0800 Subject: Check in a pristine copy of GCC 4.8.1. The copy of GCC that we use for Android is still not working for mingw. Rather than finding all the differences that have crept into our GCC, just check in a copy from ftp://ftp.gnu.org/gnu/gcc/gcc-4.9.3/gcc-4.8.1.tar.bz2. GCC 4.8.1 was chosen because it is what we have been using for mingw thus far, and the emulator doesn't yet work when upgrading to 4.9.
