Yes, that is exactly correct: it is long int or unsigned long int.

X3.159-1989, section 3.1.3.2, Integer Constants, p. 28, ll. 37--41:

	The type of an integer constant is the first of the
	corresponding list in which its value can be
	represented. ... suffixed by the letter |l| or |L|:
	|long int|, |unsigned long int|; ...

Thus, if 0x80000000 (2147483648) can be represented correctly as
a long int---e.g., on a 64-bit machine where 0x80000000 is really
0x0000000080000000---its type is `long int', otherwise its type
is `unsigned long int'.

If the number should have the type `unsigned long int', it can be
written as 0x80000000UL, 0x80000000LU, 0x80000000uL, etc.  A cast
in front of the constant will also serve (and will port to pre-ANSI
compilers).
