+From: Benjamin Barenblat <bbaren@google.com>
+Subject: Check printf format strings in str_format_convert_test
+Forwarded: yes
+Applied-Upstream: https://github.com/abseil/abseil-cpp/commit/1963f10ae5cb32a7ea6d96b928f69d3c7fba0139
+Bug-Debian: https://bugs.debian.org/1011294
+
+Don’t use generator expression to build .pc Libs lines
+
+When building pkg-config files, compute linker flags with a string
+substitution rather than the JOIN generator expression. This ensures
+that commas in linker flags don’t get treated as argument separators in
+JOIN.
+
+The author works at Google. Upstream applied this patch as Piper
+revision 450675966 and exported it to GitHub; the Applied-Upstream URL
+above points to the exported commit.
