+commit 415db7054723291042e4ff1ffa8fdd5bc8b07163
+Author: Andrey Semashev <andrey.semashev@gmail.com>
+Date:   Sat Sep 27 20:40:09 2014 +0400
+
+    Added support for extending operations to GCC atomic backend.
+    
+    Fix for #10446. Some platforms (e.g. Raspberry Pi) only support atomic ops of some particular size but not less. Use extending arithmetic operations for these platforms. Also, make sure bools are always treated as 8-bit values, even if the actual type is larger. This makes its use in atomic<>, atomic_flag and lock pool more consistent.
