I've wondered some since I began hearing about "long longs" and
"quads".  Wouldn't it make more sense for gcc to do:

	char	1 byte
	short	2 bytes
	int	4 bytes
	long	8 bytes

rather than inventing long longs?

As far as I know, this doesn't violate any C standard (I think the guarantee is

	char < short <= int <= long

), and we seemed to survive pretty well back in V7 days on the PDP11 with
int = 2 bytes and long = 4 bytes.

I realize this would break a lot of code (including much of my own, I'm sure),
but it seems it will have to be done eventually.  Is there any other reason
for not doing it?
