System: NetBSD quix 2.0G NetBSD 2.0G (QUIX) #3: Tue Aug 17 23:48:17 CDT 2004 root@quix:/local0/src/sys/arch/i386/compile/QUIX i386
Architecture: i386
Machine: i386
>Description:
	The param.h in sys/arch/arm/include/param.h uncontionally sets
        MACHINE to "arm" regardless of the actual machine in use.

	This is completely different than any other combined arch does
	(m68k, powerpc, etc) and should be cleaned up to have the same
	behavior.
	
	Most likely MACHINE/MACHINE_ARCH should be expunged completely from
	user space visibility as code should be using uname(3) to extract
	this data. 
>How-To-Repeat:
	cat > foo.c <<"EOF"
#include <sys/param.h>

char *foo = MACHINE;
EOF

gcc -dM -E foo.c |egrep MACHINE

(on an arm platform, or use a cross setup)
>Fix:
	Make this line up with other archs or expunge MACHINE/MACHINE_ARCH
	from userspace finally.
