{
 Linux system calls take arguments as follows :

   i386/m68k:

   %eax/%d0 : System call number
   %ebx/%d1 : first argument
   %ecx/%d2 : second argument
   %edx/%d3 : third argumens
   %esi/%d3 : fourth argument
   %edi/%d4 : fifth argument

  That is why we define a special type, with only these arguments
  To make it processor independent, we don't give any system dependent
  names, but the rather abstract reg1,reg2 etc;
