Date: Mon, 22 May 2006 01:16:47 -0400 From: Mike Frysinger Subject: [SDL] [patch] fix sed expression in sdl-config just noticed that sdl-config uses '[a-z]' with sed in sdl-config without forcing the locale to C ... this could cause problems with locales where the letter 'z' is not the last letter in the alphabet
