+Subject: [PATCH 1/1] Remove Werror
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+-Werror shouldn't be used in released code since it can cause random build
+failures on moderate warnings. It also depends on the used toolchain since
+different toolchains may or may not print the same warnings.

-From: Baruch Siach <baruch@tkos.co.il>
-Subject: [PATCH] Revert "Use std namespace for snprintf."
-
-This reverts commit 1c58876185d2a4ed87dac4a54b82f607e74f55fd.
-
-std::snprintf() is only available in C++11, which is not provided by
-all compilers. Since the C library snprintf() can easily be used as a
-replacement on Linux systems, this patch changes jsoncpp to use the C
-library snprintf() instead of C++11 std::snprintf(), fixing the build error
-below:
-
-src/lib_json/json_writer.cpp:33:18: error: 'snprintf' is not a member of 'std'
-
-Upstream status: sent upstream
-package/jsoncpp/0001-Revert-Use-std-namespace-for-snprintf.patch
