That becomes a long long because it won't fit anything smaller.

Here is a table, laboriously typed in by hand from the standard
(with abbreviations courtesy of me being a lazy bum).  For those
who might care, the table comes from section 6.4.4.1, integer
constants, on page 56 of the C99 standard.

For each combination of suffix and type of constant, this
table it gives the sequence of types that will be tried to
fit the constant.


Suffix		Decimal Constant		Hex/Octal Constant
==================================================================
none		int, long, long long		int, u. int, long, u. long, long long, u. long long

U		u. int, u. long, u. long long	u. int, u. long, u. long long

L		long, long long			long, u. long, long long, u. long long

UL		u. long, u. long long		u. long, u. long long

ll		long long			long long, u. long long

ull		u. long long			u. long long
