Description: Fix overflow errors with 64-bit IVs
The perl 5.12 packages are compiled with -Duse64bitint, which means that IVs
are 64-bits even on 32-bit architectures. When converting IVs, SWIG assumes
that an IV is the same size as a long, which causes OverflowErrors with
unsigned longs when the value is greater than 2^31.
.
This patch should remove those assumptions by using the "IV" type defined by
the perl headers, and explicitly checking the values are within the correct
range for the type being converted.
