 dash fails to build on Mac OS X 10.6 and earlier because it uses
 `stpncpy`:

 /install-port/logs/stdio
 {{{

 {{{

 ld: symbol(s) not found for architecture x86_64
 }}}

 The suggestion to include <string.h> is incorrect because there is no
 `stpncpy` anywhere on Mac OS X 10.6 or earlier.

 I believed that our legacy support library implemented `stpncpy` so I
 [changeset:ffd5b7c83a946c2d6f5b0de805981b02e367cc58/macports-ports added
 legacy support to dash] but in fact [ticket:69571 legacy support doesn't
 have stpncpy yet].

 gnulib contains an implementation of `stpncpy` for systems that don't have
 it, if dash uses or has interest in starting to use gnulib.

 dash doesn't seem to have an issue tracker. They track bugs on their
 mailing list. I found a mailing list post from 2022 where someone
 submitted a bunch of portability fixes, including an implementation of
 `stpncpy`:

 https://lore.kernel.org/dash/6cacf608-326e-211a-
 7d37-164041710980 at knaff.lu/

 Unfortunately nobody appears to have responded to it. Perhaps that part of
 the patch could be lifted out and added to the port, or someone could post
 a message to the mailing list redirecting the developers' attention to
 this patch.
