Subject: [PATCH] Fix complex number routines to work with signed zeros,
 changes involve: * Use boost::math::signbit rather than comparison to zero. *
 Use boost::math::changesign rather than unary negation (unary negation fails
 for Intel on Linux when the argument is a zero). * Update to use
 boost::math::isnan/isinf rather than the old code. * Update to use
 boost::math constants. Fixes #6171.
