Subject: [Qemu-devel] [PATCH] srp: Don't use QEMU_PACKED for single elements of a structured type
Date: Fri, 10 Aug 2012 22:03:27 +0200	[thread overview]
Message-ID: <1344629007-23311-3-git-send-email-sw@weilnetz.de> (raw)
In-Reply-To: <1344629007-23311-1-git-send-email-sw@weilnetz.de>

QEMU_PACKED results in a MinGW compiler warning when it is
used for single structure elements:

warning: 'gcc_struct' attribute ignored

Using QEMU_PACKED for the whole structure avoids the compiler warning
without changing the memory layout.
