* Compatibility / portability funcitons and constants for the MicroBit DAL.
#include "mbed.h"
#include "ErrorNo.h"
* Turn off warnings under gcc -Wall. We turn off unused-function for the
* entire compilation unit as the compiler can't tell if a function is
* unused until the end of the unit. The macro expansion for SVCALL()
* in nrf_soc.h and nrf_srv.h tries to leave unused-function turned off,
* but we restore the state from before the include with our diagnostics
* pop.
* It might be cleaner to add
* #pragram GCC system header
* as the first line of nrf_soc.h, but that's a different
* module ...
* The underlying Nordic libraries that support BLE do not compile cleanly with the stringent GCC settings we employ
* If we're compiling under GCC, then we suppress any warnings generated from this code (but not the rest of the DAL)
* The ARM cc compiler is more tolerant. We don't test __GNUC__ here to detect GCC as ARMCC also typically sets this
* as a compatability option, but does not support the options used...
