5934	"boost/math/tools/tuple.hpp omits ""tr1/"" from #include directive."	David Oliver <doliver@…>	John Maddock	"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!
