+Subject: [PATCH] Don't use __extension__ in C++ code
+
+A few important notes:
+
+*  __extension__ is a GNU C "alternate" keyword, not a C++ keyword.[1]
+
+*  __extension__ is designed to work on "expressions"; it does work on
+   #include_next in C mode, but it has no effect in C++ mode; the
+   warning will still appear, if enabled, even with __extension__
+   preceding #include_next.  This is because #include_next is not
+   considered an expression in C++, so the compiler attaches
+   __extension__ to the first expression of the header.
+
+All of this leads us to a build failure while building at least all
+Mozilla software.  Moz has an alternate -isystem dir searched before
+/usr/include that overrides some headers, including <features.h>.  The
+first statement in each of these headers is a #pragma, and since
+__extension__ is looking for an expression, and #pragma is a "null"
+expression, we end up with the following error:
+
+dist/system_wrappers/features.h:1:9: error: '#pragma' is not allowed here
+
+Since __extension__ has no effect on #include_next in C++ mode anyway,
+and since it can cause breakage, this commit omits __extension__ in C++
+mode.
