#2816: microsec_clock::create_time(TZ_FOR_CREATE tz) causes 64-to-32 bit warning

-----------------------------+----------------------------------------------
 resolution_traits_type::res_adjust() returns a 64 bit integer when boost
 is built for a 64 bit target. This leads to a warning about possible
 truncation when compiling the version of microsec_clock::create_time()
 that takes a single TZ_FOR_CREATE parameter with -Wshorten-64-to-32 on GCC
 4.0.1 for MacOSX. The other version of microsec_clock::create_time()
 already contains a static_cast to int that prevents this warning. The cast
 should be used in both methods:


 {{{
 int adjust =
 static_cast<int>(resolution_traits_type::res_adjust()/1000000);
 }}}

 This appears to be fixed in revision @49705 on the release branch (along
 with a good deal of additional restructuring).
