Hello boost developers,

this is my first mail to boost@lists.boost.org and it is already a bug that I found in the latest release 1.31.0 :-(

I tried to compile boost::math::asinh, boost::math::acosh and boost::math::atanh recently and got a compile error "C2039 'abs' : is not a member of ' STL'" on my MSVC6

The short answer: use a more conforming compiler.

compiler. I have STLPort 4.5.3 installed and thought, this might be the problem, but then I found out that boost::math::sinc pi and boost::math::sinhc pi compile with no errors.

The longer answer: I am updating the special functions, but the primary aim will be to add functionality for the better conforming compilers. The functions sinus cardinal and hyperbolic sinus cardinal are the last I modified before going into limbo for too long, but the other functions are scheduled to be updated. If I find some more time, I will possibly add support for some older compilers, so your input is welcome.

To make it short: asinh, acosh and atanh are using ::std::abs, ::std::sqrt and ::std::log - which are not part of the STL. To fix this problem, I have created a patch - see attached files. ^^^^^^^^^^^^^^^^^^^^^

Where?

Best regards,

Carsten Huber
