In case nobody else has mentioned it (I came in late on this one), there
is a difference between *x and x[] besides allocation and semantics for
globals: sizeof().  A lot of times I've been tempted to write

	static char *message = "hello";
	/* ... */
	write(fd,message,sizeof(message));

within a routine.  Obviously this won't work, but

	static char message[] = "hello";

will.  It's amazing how easy it is to forget this little detail and how
many times I've seen it done.  Usuaully it's much more insidious than
this example.
