Hello alsa-devel,

I've been using the alsaseq python module and I found a bug. Sometimes
the SEQ_* constants have extremely large and incorrect values. For
example, 25769803811 instead of 35. The lower 32-bits are always

Obviously, I'm running a 64-bit operating system.

The problem is that the `value` member of the `ConstantObject`
structure is an `unsigned int` whereas it should be a `long`. I've
attached a patch. It's against the latest released version, 1.0.20.
