I don't expect that this will be back ported to GCC 4.8. You also need
Binutils 2.24 for this.

but perhaps the RMs are of a different opinion here.
A back port would be quite nice for us, since we work currently on SMP support
for LEON3/4 and C11 atomic operations would be very handy for this.

This function could use a __gthread_mutex_t mutex for updates. This ends
