 While it might sound a natural choice, there is no gurantee that struct
 reg members (and so the PTRACE_REG_* accesor results) are of type register_t.
 
 There seem to be no standards defining it and the only other user that
 I can find is libproc, which uses "unsigned long".
 
 So I would suggest to make the test use %lx and explicitly cast all 
 PTRACE_REG_* values to unsigned long for the printf.
