+@item ISO C++11 compiler
+Necessary to bootstrap GCC. When using GCC to bootstrap itself we recommend 
+using GCC 4.8.5 or higher as the bootstrapping compiler. Versions of GCC

 To build all languages in a cross-compiler or other configuration where
 3-stage bootstrap is not performed, you need to start with an existing
