 The 'current_codepage' is referenced in the following code fragement in
LYCurses.c:

#if defined(WIN_EX) && defined(CJK_EX) /* 1999/08/26 (Thu) 17:53:38 */
    {
        extern int current_codepage;    /* PDCurses lib. */

        if (current_codepage == 932)
            LYcols = COLS - 1;
    }
#endif

 Just hide this fragment from compiler - eg change 1st line to
#if 0 && defined(WIN_EX) && defined(CJK_EX) /* 1999/08/26 (Thu) 17:53:38 */
 You don't need this fragment.

 As for _errno - I haven't encountered this problem (I used BCB 3.0).
 Does borland C 5.0 has <errno.h>?
 If yes, then (this is my guess) modify zutil.h
 to include <errno.h> unconditionally. By default, it contains:

#ifdef NO_ERRNO_H
    extern int errno;
#else
#   include <errno.h>
#endif

 and it looks like NO_ERRNO_H is definied for some reason.

 HTH
