 extern "C" {

 // This calls each of the compiler constructed functions referenced from pi_ctorvec.

 // These functions arrange to 'call' the appropriate constructor for the 'static' instance

 // (in fact the call may be inlined). If the class of the instance has a destructor then 

 // compiler records that this object needs 'destructing' at 'exit' time. It does this by 

 // calling the function __cxa_atexit. We provide our own definition of this.

 // 

 // This is the EABI compliant version - it uses .init_array rather than C$$pi_ctorvec

 // which means we need to do via assembler :-(
