+Subject: [PATCH 153/163] Fix build with GNU libstdc++ C++11 ABI
+
+The GNU libstdc++ that ships witch gcc 5 can be used with the same ABI as
+older versions, or with a new ABI which is conformant to the C++11 standard.
+LyX did not build if the latter was used:
+https://kojipkgs.fedoraproject.org//work/tasks/1267/9651267/build.log
+
+This is now fixed by detecting the ABI version and disabling the wrong forward
+declarations. At the same time, STD_STRING_USES_COW is switched off for the
+C++11 ABI version, because the std::basic_string implementation is now C++11
+conformant. Since the GNU libstdc++ can also used by other compilers such as
+clang, we must not test for the compiler version.
