From f66724c99a322ec147b0297cba4334c589883b47 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Thu, 15 Jul 2010 22:28:02 +0200 Subject: Add new user mode option -ignore-environment An empty environment is sometimes useful in user mode. The new option provides it for linux-user and bsd-user (darwin-user still has no environment related options). The patch also adds the documentation for other environment related options.
