Hi all,

It would be nice if seed_rng used CryptGenRandom (or something similar)
on Windows instead of trying to open /dev/urandom.

The patch for seed_rng.hpp at:

http://www.dynaroad.com/win.diff

tries to use CryptGenRandom when BOOST_WINDOWS and _WINDOWS_ (i.e.
windows.h has been included before uuid.hpp) are defined.

This seems to work on Windows XP SP2 and Visual Studio 2005.

Cheers,
