Subject: [Boost-commit] svn:boost r78193 - in trunk: boost/math/bindings boost/math/bindings/detail boost/math/concepts boost/math/constants boost/math/special_functions boost/math/special_functions/detail boost/math/tools libs/math/test
From: john_at_[hidden]
Date: 2012-04-25 13:16:12
Author: johnmaddock
Date: 2012-04-25 13:16:09 EDT (Wed, 25 Apr 2012)
New Revision: 78193
URL: http://svn.boost.org/trac/boost/changeset/78193
Log:
Add code to force initialization of constants prior to the start of main().
Rename "do_nothing" to "force_instantiate" which better describes what it does.
Fix up the resulting failures.
