Subject: Re: [PATCH] Remove last reference to LDFLAGS_BLOB
Date: Wed, 20 Oct 2004 15:59:27 -0200 [thread overview]
Message-ID: <20041020175927.GE14780@logos.cnet> (raw)
In-Reply-To: <4175C6E2.1080201@quark.didntduck.org>
No, do not remove that initramfs_data.S section!
People with older binutils (like me) rely on it.
Make it obsolete on 2.7.x.
