Re: [Bug-apl] cast from pointer to smaller type 'int'

[Xiao-Yong Jin]

Should have got back to you sooner, but static_cast is not allowed between 
pointer types and non-pointer types.

Thread_context.cc:73:11: error: static_cast from 'pthread_t' (aka 
'_opaque_pthread_t *') to 'int' is not allowed
       << static_cast<int>(thread)
          ^~~~~~~~~~~~~~~~~~~~~~~~

I need reinterpret_cast<size_t> here.  I cannot reinterpret_cast<int> either, 
because of the difference in size.
