	---help---
		This setting means (1) your C++ compiler has sizeof(_Bool) == 8, (2)
		your C compiler supports the C99 _Bool intrinsic type, and (2) that
		the C99 _Bool type also has size 1.

config HAVE_CXX
	bool "Have C++ compiler"
	default n
	---help---
		Toolchain supports C++ and CXX, CXXFLAGS, and COMPILEXX have been
		defined in the configurations Make.defs file.

		runtime support function.
