I do not know anything but on GNU/Linux, the definitions of these are:

    static const mask upper     = _ISupper;
    static const mask lower     = _ISlower;
    static const mask alpha     = _ISalpha;
    static const mask digit     = _ISdigit;
    static const mask xdigit    = _ISxdigit;
    static const mask space     = _ISspace;
    static const mask print     = _ISprint;
    static const mask graph     = _ISgraph;
    static const mask cntrl     = _IScntrl;
    static const mask punct     = _ISpunct;
    static const mask alnum     = _ISalnum;

While on FreeBSD, it is:

    static const mask upper     = _CTYPE_U;
    static const mask lower     = _CTYPE_L;
    static const mask alpha     = _CTYPE_A;
    static const mask digit     = _CTYPE_D;
    static const mask xdigit    = _CTYPE_X;
    static const mask space     = _CTYPE_S;
    static const mask print     = _CTYPE_R;
    static const mask graph     = _CTYPE_G;
    static const mask cntrl     = _CTYPE_C;
    static const mask punct     = _CTYPE_P;
    static const mask alnum     = _CTYPE_A | _CTYPE_D;

See how on FreeBSD alnum is defined what you want it.
