[C++-sig] bpl on sun errors

[FLETCHER, Shayne, FM]

Dear All:

I have been trying to compile the v2 boost_python shared library on Solaris
using Sun Workshop 6 (__SUNPRO_CC=0x530) and 7 (__SUNPRO_CC=0x540). I can
report that with a little massaging (right or wrong), most of the source
files compile. The following problem though has stopped me in my tracks:
"object/enum.cpp" produces 

"object/enum.cpp", line 141: Error: Overloading ambiguity between
"boost::python::handle<_typeobject>::handle<boost::python::detail::borrowed<
_typeobject>>(boost::python::detail::borrowed<_typeobject>*)" and
"boost::python::handle<_typeobject>::handle(const
boost::python::handle<_typeobject>&)".
"object/enum.cpp", line 141: Error: Cannot use
boost::python::detail::borrowed<_typeobject>* to initialize
boost::python::handle<_typeobject>.
"object/enum.cpp", line 142: Error: Overloading ambiguity between
"boost::python::handle<_typeobject>::handle<boost::python::detail::borrowed<
_typeobject>>(boost::python::detail::borrowed<_typeobject>*)" and
"boost::python::handle<_typeobject>::handle(const
boost::python::handle<_typeobject>&)".
"object/enum.cpp", line 142: Error: Cannot use
boost::python::detail::borrowed<_typeobject>* to initialize
boost::python::handle<_typeobject>.
"object/enum.cpp", line 188: Error: Cannot cast from
boost::python::api::proxy<boost::python::api::attribute_policies> to
boost::python::extract<boost::python::dict>.
"object/enum.cpp", line 199: Error: Overloading ambiguity between
"boost::python::handle<_typeobject>::handle<boost::python::detail::borrowed<
_typeobject>>(boost::python::detail::borrowed<_typeobject>*)" and
"boost::python::handle<_typeobject>::handle(const
boost::python::handle<_typeobject>&)".
"object/enum.cpp", line 199: Error: Cannot cast from
boost::python::detail::borrowed<_typeobject>* to
boost::python::handle<_typeobject>.
"object/enum.cpp", line 201: Error: Cannot cast from
boost::python::api::proxy<boost::python::api::attribute_policies> to
boost::python::extract<boost::python::dict>.

The statements at lines 141 and 142 giving rise to the first of the
"overloading ambiguity" errors are:

      type_handle metatype(borrowed(&PyType_Type));
      type_handle base(borrowed(&enum_type_object));

Does anyone have any suggestions ?
