>Description:
        strnvis(3) has different argument from OpenBSD.

        It is declared in <vis.h> as:

                int     strnvis(char *, size_t, const char *, int);

        But, originally on OpenBSD:

                int     strnvis(char *, const char *, size_t, int);

        Compiler shows warning but not error in general.

>How-To-Repeat:
        Compile openssh 5.8p2 outside of pkgsrc and start sshd.  It would
        crash on logging to syslog at first time.
>Fix:
        I don't know this difference is intentional or not.  But it is too
        bad that the same function has different argument.
