 octonion_test.cpp cannot be compiled neither gcc 3.2
 nor Intel compiler because of the possible bug in
 boost/math/special_functions/sinc.hpp and in
 boost/math/special_functions/sinhc.hpp. Here are given
 the command line and the error (got from bjam build
 from “status” directory):

 /home/users/vsysoltx/boost_loki/boost_1_30_0/boost/ma
 th/special_functions/sinc.hpp:109: no
    matching function for call to `abs(const
 boost::math::octonion<float>&)'
 <internal>:109: candidates are: int std::abs(int)
 /usr/include/c++/3.2/cstdlib:119:                 long int
 std::abs(long int)

 (float)
 /usr/include/c++/3.2/cmath:95:                 long double
 std::abs(long
    double)

 The reason why compiler cannot find the appropriate
 boost::math::abs<T>(octonion<T>) definition is that here
 is used ::abs directive inside function. When this
 directive is used in the function definition, it hides the
 names from outermost namespaces. I don’t know why, I
 haven’t found this in standards, but that’s true both for
 gcc 3.2 and for Intel compiler. To compile these files I
 used a patch which is attached. In it the using directives
 are simply carried out of the function definition. That’s
 work with both compiler.

Comment:

 I'm closing this as obsolete: the test does now pass with gcc-3.x and
 current Intel compilers.
