Both Sun and Pgi on Linux correctly put typeinfo into the std

namespace, but function_base keys off the
BOOST_NO_EXCEPTION_STD_NAMESPACE macro instead of the
BOOST_NO_STD_TYPEINFO macro.  The attached patch changes
function_base to use the typeinfo macro.  Because eVC 4.2 doesn't
put typeinfo into the std namespace, I need to define
BOOST_NO_STD_TYPEINFO only for this eVC version.
