Milestone:  To Be Determined                        |   Component:  math       
  Version:  Boost 1.47.0                            |    Severity:  Problem

----------------------------------------------------+-----------------------
 In version_1_47_0 and the current head (Revision 74542),
 {{{boost/math/tools/tuple.hpp}}} includes at line 34 the C++11 header
 {{{<tuple>}}}, rather than the TR1 header {{{<tr1/tuple>}}}:
 {{{
 #elif defined(BOOST_HAS_TR1_TUPLE)

 #include <tuple>

 namespace boost{ namespace math{

 using ::std::tr1::tuple;

 // [6.1.3.2] Tuple creation functions
 using ::std::tr1::ignore;
 using ::std::tr1::make_tuple;
 using ::std::tr1::tie;
 using ::std::tr1::get;

 // [6.1.3.3] Tuple helper classes
 using ::std::tr1::tuple_size;
 using ::std::tr1::tuple_element;

 }}

 #elif  ...
 }}}

 With gcc 4.4.3, without {{{std=c++0x}}} or {{{std=gnu++0x}}} specified,
 this produces a compatibility warning; other compilers/versions are likely
 to fail to find the header.

 Changing the line to:
 {{{
 #include <tr1/tuple>
 }}}
 makes the compilation (and my unit tests) successful.

 Cheers!

 David Oliver.
