Needed for calling broken functions in 3td party libraries. There are still
libraries around which won't mark unmodified parameters with "const" to be
compatible with older compilers. 

I am not saying it's good. And of course the library vendors are just hiding
there laziness behing a "compatiblity" argument:

#if COMPILER_X_VERSION < 2.0
#define const
#endif
