[Bug-apl] SVN 984 changes

[Juergen Sauermann]

Hi, I would like to inform you about 2 changes that I made in SVN 984. 1. Use of C++ casts instead of C casts I have replaced every old-style C cast by either a C++ cast (static_cast<>(), reinterpret_cast<>(), or const_cast<>()). The reason for this change is to keep up with the changes in the C++ language. Also, the Makefiles were changed to not allow C casts any longer. 2. APL_Float as class. I have change the code so that one can use a class  APL_Float instead of the previous typedef double APL_FLoat. An example class is provided in file APL_Float_as_class.hh and the decision if a typedef or a class shall be used is made in APL_types.hh via  #define APL_Float_is_class 0 or 1. This change simplifies, for example, the introduction of libraries for higher precision arithmetic. I hope all this still compiles on your machines. Make clean and a new ./configure is required after SVN up. Best Regards, Jürgen Sauermann
