Anyone writing signal code w/o using sigaction() is asking for trouble.
Never count on how signal() behaves. Of course on some platforms,
sigaction() is somewhat flakey, (HP/UX and SunOS 4), but it's good
accross any truely POSIX.1 platform.

NetBSD has dirent/DIR directory access. There are minor differences
in some structure members, but if you code to the command and SysV
supported d_name/d_reclen and use the access functions, you're okay.

"Late" BSD's including NetBSD have termios. Agreed though, termios is
much better than sgtty.
Linux also implements the more interesting BSD system calls such as
mmap(), so I'm happy!
I enjoy mmap(), it's way easier to use then SYSVSHM and has better
charecteristics (like auto cleanup by the kernel).
Anyways, just more evidence that the more things go on, the more similar
they get...so use what you like and are happy with and I will to.
