From 7b118eccac021934f7731396767dd0b50320acc6 Mon Sep 17 00:00:00 2001 From: Franklin Wei Date: Mon, 17 Jun 2019 23:04:42 -0400 Subject: configure: add --32-bit option to build a 32-bit simulator/application I use this to test duke3d in the sim, because it does some nasty pointer arithmetic with 32-bit ints. Should be useful for other things as well.
