Good.

I suppose the compiler can't know if the 'raise' will terminate the 
program, so it needs the 'return'.

Good question. I had to search for the answer and it seems it does 
indeed the same:

http://www.gnu.org/software/libc/manual/html_node/Termination-Internals.html
"When a process terminates for any reason -- either because the program 
terminates, or as a result of a signal -- the following things happen:"
