Comment(by jdccdevel@…):

 I am compiling with gcc version 4.2.4 on AIX.

 I was able to remove the dependency on pthreads by building with
 BOOST_DISABLE_THREADS defined in boost/config/user.hpp

 This is (thankfully) sufficient for my purposes for now.

 I Definitely concur that threading=single is a highly misleading option in
 this case. If there needs to be two options, "threading=single" should
 renamed to "threading=default" as you implied above. Not being familiar
 with the internals of the boost build system, I would have expected
 threading=single to prevent the setting of the "BOOST_HAS_THREADS" define
 in all cases. However this is obviously not happening.

 I understand that this is something of a unique case, as I cannot have a
 dependency on pthreads. However, If nothing else, I do believe that this
 should be more explicitly documented in the "bjam --help" documentation
 and elsewhere.
