hmm - it was mis-directed....

The current version of ncurses is 5.3 (20021012)
There's an faq at

There's no reason to change the values, since event.bstate is an unsigned
long, and the mask constants also are.  (It's been that way for quite a
while):

typedef unsigned long mmask_t;

typedef struct
{
    short id;           /* ID to distinguish multiple devices */
    int x, y, z;        /* event coordinates (character-cell) */
    mmask_t bstate;     /* button state bits */
}
MEVENT;
