Comment (by mascguy):

 The change to use `legacysupport` fixes this port for macOS releases from
 10.7 through 10.12, so we're in great shape.

 For 10.6, there's still a build issue, related to `dprintf`:

 {{{
 [...]
 unsquashfs.c: In function ‘pseudo_print’:
 unsquashfs.c:3478: warning: implicit declaration of function ‘dprintf’
 [...]
 Undefined symbols:
   "_dprintf", referenced from:
       _pseudo_print in unsquashfs.o
       _generate_pseudo in unsquashfs.o
 }}}

 That might be fixable too, given the earlier implicit function declaration
 warning. But overall, looking good!
