[boost] [OT] Enabling exported templates with Intel for Windows.

Hi, I know this is OT, but I can't think of a better place to ask. Intel on Linux supports exported templates with the -export and -export_dir options. Supposedly, Intel for Windows also supports exported templates, as an "undocumented and unsupported" feature.(http://www.comeaucomputing.com/iso/promises.html) Could someone tell me how to enable export for Intel on Windows, and how to specify the location of the template implementations? I couldn't find anything about it on the web. Is it a big secret? Jonathan
