Probably. I don't have access to that configuration though. Presumably
the definitions for the inv hyperbolics come from Glibc, so the question
is whether STLPort pulls them into namespace std or not.

BOOST_HAS_INV_HYPERBOLIC is not being defined, so the using decls aren't
defined so we get a "using std::cosh;"

Maybe the first test in boost/numeric/interval/detail/bugs.hpp needs to
be extended to cover this config?  GCC 2.95 (without STLPort) defines
__USE_MISC when std headers are included (I'm not sure exactly where it
gets set). I guess STLPort takes some detour that prevents it being
defined.
