Subject: [PATCH v2 02/20] gcc-plugins: Detail c-common.h location for GCC 4.6
Date: Fri, 26 May 2017 13:17:06 -0700	[thread overview]
Message-ID: <1495829844-69341-3-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1495829844-69341-1-git-send-email-keescook@chromium.org>

The c-common.h file moved in stock gcc 4.7, not gcc 4.6. However, most
people building plugins with gcc 4.6 are using the Debian or Ubuntu
version, which includes a patch to move the headers to the 4.7 location.
In case anyone trips over this with a stock gcc 4.6, add a pointer to the
patch used by Debian/Ubuntu.
