> The C++ specification states:
> The macro ATOMIC_FLAG_INIT shall be defined in such a way that it can be used to initialize
an object of type atomic_flag to the clear state. The macro can be used in the form: "atomic_flag
guard = ATOMIC_FLAG_INIT; "It is unspecified whether the macro can be used in other initialization
contexts." 
> Clang catches this (although reports it erroneously as a braced scaled init issue) and
refuses to compile libprocess.
