From 66948f7e8c3e2e89c5fd8a7b0b4c7bc112553aa0 Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Fri, 13 Feb 2009 20:20:21 +0000 Subject: This target is dead. The company is dead. It causes builds to fail, and that is not a problem we need to have. Removing it to remove the problems it causes. Signed-off-by: Ronald G.
