Determining win32 dll dependency

[Robin Becker]

A client requested that I send MSVCR71.DLL along with the rest of an application 
as it wasn't present on his machine.

That is allowed as

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_c_run.2d.time_libraries.asp

seems to explicitly allow for this.

I would like to automate my build script to include this file, but cannot think 
of an automatic way to determine which of msvcr70/71.dlls  .... are needed.
