I think you are wrong as far as I can see the AMIGA 3000 UX is not compliant, 
for example:

The current ABI defines the structure sigaction (see sys/signal.h)
to be:

	struct sigaction {
		void (*sa_handler)();
		sigset_t sa_mask;
		int sa_flags;
	}

yet the AMIGA defines it as:

	struct sigaction {
		int sa_flags;
		void (*sa_handler)();
		sigset_t sa_mask;
		int sa_resv[2];
	}

Also the online manual page for sigaction on the AMIGA states:

	The sigaction structure includes the following members:

		void		(*sa_handler)();
		sigset_t	sa_mask;
		int		sa_flags;

There is no mention of int sa_resv[2];

On the AMIGA we have here, uname -a gives 

	UNIX_Sytem_V localhost 4.0 1.1 Amiga m68020

This could be wrong though as the sytem here has a m68030 running at 25MHz.

Obviously, these are my opinions and do not reflect the opinions of my 
employers who just so happen to produce a version of V.4 for the Motorola 68k.
