[Boost-commit] svn:boost r80915 - trunk/boost/geometry/algorithms

Subject: [Boost-commit] svn:boost r80915 - trunk/boost/geometry/algorithms
From: bruno.lalande_at_[hidden]

Author: bruno.lalande
Date: 2012-10-09 18:07:30 EDT (Tue, 09 Oct 2012)
New Revision: 80915
URL: http://svn.boost.org/trac/boost/changeset/80915

Log:
Made dispatch::for_each able to find out the geometry constness by itself, and used boost::is_const instead of dedicated overloads.
