      The short answer: use a more conforming compiler.

      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.

                                                    ^^^^^^^^^^^^^^^^^^^^^
