Release candidate files for 1.65.0 are available at
http://boost.cowic.de/rc/
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:

I also see compilation failures with gcc 4.6 in C++11 mode:

Ouch. Can anybody else repro this? Oliver, thoughts?
I think the problem is in Boost.Thread, boost/thread/detail/invoke.hpp. I
emailed Vicente, no response so far.
I'll try to come up with a patch.
