[Boost-users] [boost.asio] Timer.5 example code: 8 compiling errors

Subject: [Boost-users] [boost.asio] Timer.5 example code: 8 compiling errors

Hi there,

When compiling the example program "Timer.5 - Synchronising handlers in
multithreaded programs" of boost asio 1_44 with MSVC 2008 professional on
Window XP professional, I got 8 compiling errors, although the code executes
without any problem. Is it safe to ignore those warnings?

BTW: the Boost 1_44 was installed on my machine with the Binary Installers
recommended in boost documentation.

Thanks,
Robert
