Hi!

I had the same problem. This seems to be an MS bug. In our case using VC++
7.1 we compiled an application with 4 byte struct member alignment and
were unable to link it. Using the dependency walker has shown, that this
symbol is differently exported in program_options.dll as expected from the
linker which links to the DLL. I remember that I have written what we did to
resolve the problem.

Here is my previous post:
http://groups.google.am/group/boost-list/browse_frm/thread/3ec1940f2517241f/17a0cfe15fffe357?tvc=1#17a0cfe15fffe357

We had the similar issue with boost::filesystem and 4 byte alignment as
well.

With Kind Regards,
Ovanes
