Use of uint and int

[Popog]

Because the size of uint and int aren't specified in the go-spec (they could be either 32 or 64 bit), and the size of int is specified for the Windows API to be 32 bit, I would suggest using int32 and uint32 for the Windows structures.

Thanks for the suggestion, but I would assume the current implementation with 32 bit int in the gc tool chain won't change any time soon.

I'd say let's wait with such a change in Walk until it is really needed.

Just to clarify: I'm rather busy with other projects right now and there are more pressing things to do for Walk, but if you would like to do this change, I will happily accept a pull request :)
