+=== 0001-configure.patch ===
+From dbe341cf6a77bb28c5fdf8b32dcb0ff1c2a27348 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] c++: Fix --disable-bootstrap with older g++.
+
+Previously I had AX_CXX_COMPILE_STDCXX in the gcc directory configure, which
+added -std=c++11 to CXX if needed, but then CXX is overridden from the
+toplevel directory, so it didn't have the desired effect.  Fixed by moving
+the check to the toplevel.  Currently it is only used when building GCC
+without bootstrapping; other packages that share the toplevel directory
+can adjust the condition if they also want to require C++11 support.
 
+ChangeLog:
+
+       * configure.ac: Check AX_CXX_COMPILE_STDCXX if not bootstrapping.
+       * configure: Regenerate.
+
+gcc/ChangeLog:
+
+       * aclocal.m4: Remove ax_cxx_compile_stdcxx.m4.
+       * configure.ac: Remove AX_CXX_COMPILE_STDCXX.
+       * configure: Regenerate.
