The implicit declaration comes from ax_with_curses.m4 checking the existence or ABSENCE of ncursesw.h file. 

So it seems quite natural hat the function may be undefined if the header file is not present.

    media-radio/tlf: Skip check for implicit function declaration in config logs
    
    ax_with_curses.m4 ifrom autoconf-archive checks potential available
    ncursesw header file locations. If header file is not found the check
    results in an implicit function declaration.
