We have strnvis(), but it is not suitable.  We got strnvis() from
NetBSD, and its arguments are in a different order from OpenBSD's
version.  See the archive for earlier discussions (and crash reports :)
about this.

I recommend adding the line:

CONFIGURE_ENV=		ac_cv_func_strnvis=no

to the port Makefile, just as with security/openssh-portable.
