Summary: According to the C++ standard <stdbool.h> isn't allowed to define `true` `false` or `bool`. However these macros are sometimes defined by the compilers `stdbool.h`. Clang defines the macros whenever `__STRICT_ANSI__` isn't defined (ie `-std=gnu++11`). New GCC versions define the macros in C++03 mode only, older GCC versions (4.9 and before) always define the macros. This patch adds a wrapper header for `stdbool.h` that undefs the required macros.
