I'll have a look.

Martin, look at the sources!  I mean look at "uname.c" of the sh-utils
1.16.  You will find a couple of lines:

#ifdef HAVE_SYS_SYSTEMINFO_H
# include <sys/systeminfo.h>
#endif

...

#if defined (HAVE_SYSINFO) && defined (SI_ARCHITECTURE)
  if (sysinfo (SI_ARCHITECTURE, processor, sizeof (processor)) == -1)
    error (1, errno, _("cannot get processor type"));
#else
  strcpy (processor, "unknown");
#endif

So where is your "processor" field of structure utsname??

It does not! Is "uname -p" a C structure?  The "-p" is an option to
the uname /program/.  And the uname program will call the function
sysinfo() if this is available, otherwise it will print "unknown".
The uname program doesn't even touch a struct utsname when getting
the processor type.

If you still don't believe me, look at /usr/include/utsname.h of 
your Linux box and you won't find a "processor" field there.

With the new MiNTLib "uname -p" will work, on Linux it doesn't because
Linux doesn't implement the sysinfo function. What do you want more?

Ciao
