OpenVMS patches for compiler issues workarounds

[artyomtnk@…]

Hello,

This patch provides fixes for OpenVMS platform/DECCXX compiler.

It is very important for the organization I work for to submit them to upstream Boost in order to make an upgrade to future Boost versions simpler.

This patch related to ticket: #4473

Thanks,

Artyom

Please, could you provide the compile errors you get?

I'll provide them as soon as I get to OpenVMS (I think on Sunday)

Not sure if you're still looking for the compile errors (these changes still seem applicable in boost 1.46.1 on OpenVMS v8.3 on Alpha, with C++ V7.3-015)

For the change in the future.hpp file, the errors I get without the fixes are:

                        locks[i]=boost::unique_lock<boost::mutex>(futures[i].future->mutex);
.................................^
%CXX-W-REFTEMPORARY, initial value of reference to non-const must be an
          lvalue

                        locks[i]=boost::unique_lock<boost::mutex>(futures[i].future->mutex);
................................^

          [with Mutex=boost::mutex]" is inaccessible
at line number 422 in file BOOST_1_46_1:[boost.thread]future.hpp;1

The errors in thread_data.hpp:

            this_thread::sleep(get_system_time()+rel_time);
................................................^
%CXX-E-NOMATOPRFUN, no operator "+" matches these operands

I haven't been able to repro the error in thread.cpp
