New Revision: 45445
URL: http://svn.boost.org/trac/boost/changeset/45445

Log:
Consistently use symlinks when installing Boost.

    * Jamroot: use symlink, not hardlink
    * tools/build/v2/tools/symlink.jam: Implement fallback
    for doing symlinks on Windows.

Fixes #1902.  Thanks to Frank Mori Hess for the patch.
