IIRC originally when I added ctypes, name:pcchar was meant to be the translationfrom "const char*
name".

C const back then translated to nothing (since Pascal CONST was still by ref
then), and it was an attempt to at least register the fact that the
declaration had CONST in C. 

This because some of the problems of "CONST" on
different architectures were already known by then.
