#13131: move_if_not_lvalue_reference undefined under
BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE
------------------------------+---------------------------
 Reporter:  ryan.johnson@…    |      Owner:  Ion Gaztañaga
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  move
  Version:  Boost 1.60.0      |   Severity:  Regression
 Keywords:                    |
------------------------------+---------------------------
 Defining BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE causes the following program
 to fail compilation for boost-1.60.0 and newer:

         #define BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE

         #include <boost/thread.hpp>

         int main() { }

 NOTE: this regression was reported over a year ago on the mailing lists
 but the message received no reply and nobody ever filed a bug.
 https://lists.boost.org/boost-users/2015/12/85457.php

 It appears the fix is simple: move the definition of
 move_if_not_lvalue_reference() outside the #ifdef for
 BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE. Untested patch attached.
