From f3da24c4c311766d8d2f76d008b0e6a652300dd0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?M=C3=A5ns=20Rullg=C3=A5rd?= Date: Wed, 13 Jan 2010 03:11:02 +0000 Subject: [PATCH] SIPR: kill variable-length arrays Two of these are in fact constant size, so use the constant instead of a variable in the declarations. The remaining one is small enough that always using the maximum size is acceptable.
