From af1e42f3663dcd8159beaaa0859821132e24b852 Mon Sep 17 00:00:00 2001 From: ed Date: Sat, 5 Nov 2011 07:18:53 +0000 Subject: Add static keywords to variables and functions where possible in games/. This allows us to detect unused functions and variables and allows the compiler to do a better job at optimisation. --- games/fortune/fortune/fortune.c | 186 ++++++++++++++++++++-------------------- games/fortune/unstr/unstr.c | 12 +-- 2 files changed, 98 insertions(+), 100 deletions(-) (limited to 'games/fortune') diff --git a/games/fortune/fortune/fortune.c b/games/fortune/fortune/fortune.c index 65ae35e..e93b0e7 100644 --- a/games/fortune/fortune/fortune.c +++ b/games/fortune/fortune/fortune.c @@ -97,73 +97,71 @@ typedef struct fd { struct fd *next, *prev;
