+From: Benjamin Barenblat <bbaren@google.com>
+Subject: Set package configuration options
+Forwarded: not-needed
+
+Configure Abseil for Debian.
+
+  - Set the SONAME appropriately.
+
+  - To minimize the possibility of future ABI breakage, treat absl::any,
+    absl::optional, absl::string_view, and absl::variant as their own types
+    (rather than aliases for the std:: versions), and compile everything in an
+    inline namespace.
+
+  - Enable upstream's hardened build mode.
+
+  - Disable Intel SSE2 on i386, since Debian supports some i386 processors
+    without that extension. Keep it enabled on amd64, since all amd64 processors
+    have it.
+
+  - Disable Intel SSSE3 entirely, since no i386 processor supports it and Debian
+    supports amd64 processors without it.
