We have <boost/cstdint.hpp>, yes, although in this specific case I think I 
want just

#if INT_MAX >= 0x7FFFFFFF

typedef int count_type;

#else

typedef long count_type;

#endif

I'll fix this for 1.34. In the meantime, ...

... the 'int' patch seems to be the way to go. 'ld*' might not work on 
PPC32, and 64 bits are an overkill for the reference count, anyway.

You may want to try shared_ptr_mt_test and weak_ptr_mt_test, if you haven't 
already. These aren't being run by default.
