From 9010772cdff36072dd509ec72c1a55fccde8e58e Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 6 Jan 2006 00:18:54 -0800 Subject: [PATCH] uml: Add static initializations and declarations Some structure fields were being dynamically initialized when they could be initialized at compile-time instead. This also makes some declarations static (in the C sense).
