+Subject: [PATCH 11/46] gcc-poison-dir-extend
+
+Add /sw/include and /opt/include based on the original
+zecke-no-host-includes.patch patch.  The original patch checked for
+/usr/include, /sw/include and /opt/include and then triggered a failure and
+aborted.
+
+Instead, we add the two missing items to the current scan.  If the user
+wants this to be a failure, they can add "-Werror=poison-system-directories".
