6.4.8 ctype.h functions

If you look into ctype.h you will see that the functions in there are just macros - and that they are duplicate in the library as functions. This is NOT a mistake. The ANSI standard requires such macros to be duplicate as functions.

And remember: These functions are affected by the setlocale() call.
