+
+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".

+Subject: [PATCH 15/39] gcc: Fix argument list too long error.
+
+There would be an "Argument list too long" error when the
+build directory is longer than 200, this is caused by:
+
+headers=`echo $(PLUGIN_HEADERS) | tr ' ' '\012' | sort -u`
+
+The PLUGIN_HEADERS is too long before sort, so the "echo" can't handle
+it, use the $(sort list) of GNU make which can handle the too long list
+would fix the problem, the header would be short enough after sorted.
+The "tr ' ' '\012'" was used for translating the space to "\n", the
+$(sort list) doesn't need this.
