>Description:
        sysutils/p5-Sys-Utmp dectalres its own utmpname() function
        which returns void.

        /usr/include/utmp.h declares utmpname() as returning int.

        Bang.

>How-To-Repeat:
        I use pkg_comp with NetBSD 4.0 release sets installed, and libkver.
        This makes a NetBSD 4.0 release environment (I don't use x* sets,
        but pkgsrc modular xorg, but that is irrelevant here).  In fact,
        with the possible exception of "4.0 release" all of this is irrelevant.

        In that environment I see ...

        Line 64 of (the NetBSD 4.0) /usr/include/utmp.h is

int utmpname(const char *);

        The error occurs with ...

static char _ut_name[] = _PATH_UTMP;

void utmpname(char *filename)
{
   strcpy(_ut_name, filename);
}

>Fix:
        Why does this not use utmpname() from libwhatever ???
