From 3808cb7a451a032c9181e6b3ed3f88b62eb46ee7 Mon Sep 17 00:00:00 2001 From: Loïc Minier Date: Fri, 14 Oct 2011 00:06:38 +0200 Subject: Avoid warnings by using format(__printf__) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building sandbox, barebox is built with -Dprintf=barebox_printf as to not collide with the printf provided by libc. This would also match the format(printf) function __attribute__. Since gcc documents that __printf__ can be used instead of printf as a format attribute, use this instead and avoid a lot of noisy warnings. NB: this relates to 6b082cfe9f9b5b2bea294918ad916c739490cea7 which was an earlier attempt at solving this, which got reverted due to other regressions.
