Description

**Reported in Launchpad by George last update 15-11-2017 00:29:51

It would appear this has also happened on Sparc:

class time_collector::time_collector_lock field has to be marked as mutable. And in 5.7 fixed by removing atomic operation fallbacks.

There's a solution mentioned on Stackoverflow:
http://stackoverflow.com/questions/11501971/working-around-invalid-conversion-from-const

I've combined the portability patch and made one for the time collector bug as well, please see attached patch.
It as made for 5.5.29-rel4
