12639	Boost.Spirit + BOOST_DISABLE_THREAD problem	anonymous	Joel de Guzman	"While updating the version of Boost used by some older code, I ran into a compiler-error with respect to Boost.Spirit.  My code is explicitly defining 'BOOST_DISABLE_THREAD' to avoid linking in the threading library.

I tracked down the error to line 13 of
https://github.com/boostorg/spirit/blob/develop/include/boost/spirit/home/classic/utility/scoped_lock.hpp

In the latest check-in (July 2015), the ""#include <boost/thread/lock_types.hpp>"" line was added.  This line causes a compile error when 'BOOST_DISABLE_THREAD' is defined.  (It indirectly includes other headers which 'require' the Boost.Thread library.)

I would blindly suggest that wrapping line 13 in a ""#ifndef BOOST_DISABLE_THREAD"" seems to solve the problem?
