Subject: [Boost-commit] svn:boost r83411 - in trunk/boost: . detail
From: john_at_[hidden]
Date: 2013-03-12 05:24:09


Author: johnmaddock
Date: 2013-03-12 05:24:08 EDT (Tue, 12 Mar 2013)
New Revision: 83411
URL: http://svn.boost.org/trac/boost/changeset/83411

Log:
Remove support for no numeric_limits: the old header was not Boost licence compatible, and is almost certainly no longer used by anyone anyway.
Removed:
