From 949254a2e7152fdff25792a2fdd680b4f2cbae7e Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Wed, 16 Nov 2011 16:06:42 -0500 Subject: docs: --target versus --host In the very beginnings, eons ago, autotools also got confused by this whole build vs. host vs. target, and got it wrong. Now they fixed it, but they want to keep backward compatibility, so the --target is still recongised, although ./configure will complain if you do so. It is better to use --host.
