However, with both clang 3.7 and gcc 5.2 the following program fails to compile:

#define BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE
#include <boost/thread.hpp>
int main() { }

This works fine with the same compilers and boost 1.59.

The difference seems to be caused a change to boost/thread/detail/thread_group.hpp to use boost::csbl::unique_ptr<> instead of std::auto_ptr<>.

Diff showing the change between 1.59 and 1.60 in thread_group.hpp and the compiler error messages below.

Regards,

Jan Mikkelsen

As always, the release managers would appreciate it if you download
the candidate of your choice and give building it a try. Please report
both success and failure, and anything else that is noteworthy.

This helps ensure the candidates build OK before we push them out to SourceForge.

The files (and associated md5s) are:
MD5 (boost_1_60_0_rc1.7z) = 7ce7f5a4e396484da8da6b60d4ed7661

MD5 (boost_1_60_0_rc1.zip) = 0cc5b9cf9ccdf26945b225c7338b4288

Thanks!
