+Plain integer decimal literals that are above the largest representable
+plain integer (e.g., 2147483647 when using 32-bit arithmetic) are accepted
+as if they were long integers instead.  Octal and hexadecimal literals
+behave similarly, but when in the range just above the largest representable
+plain integer but below the largest unsigned 32-bit number (on a machine
+using 32-bit arithmetic), 4294967296, they are taken as the negative plain
+integer obtained by subtracting 4294967296 from their unsigned value.  There
+is no limit for long integer literals apart from what can be stored in
+available memory.  For example, 0xdeadbeef is taken, on a 32-bit machine,
+as the value -559038737, while 0xdeadbeeffeed is taken as the value
+244837814107885L.
