SubjectRe: SCO's infringing files list
One thing I noticed.

I'm looking at include/signal.h from linux-0.01 and the definition of the
signal() function, the prototype in include/signal.h is

void (*signal(int _sig, void (*_func)(int)))(int);

I then take a look in my copy of UNIX Network Programming by W. Richard
Stevens from 1990, and notice that he on page 46 says this :

"...
A process specifies how it wants a signal handled by calling the signal
system call.

#include <signal.h>

int (*signal (int sig, void (*func)(int)))(int);

..."


The return type here is "int" while Linus originally made the return type
"void". If Linus had copied signal.h from UNIX the return type would have
been "int"...
