This is often called the XY Problem, see

Sorry for the noise, but I couldn't help myself.

That's impossible due to the data model of any distributed version
control system: since all replicas of a repository must have the same
data where it's really the same, the minimal unit of sharing history
(pushing, fetching and -- by extension -- cloning) is a commit.
Since any commit is a snapshot of the whole project, it's impossible to
clone something which is just a part of it.

On the other hand, you might have fallen a victim of a popular syndrome
of telling us your solution for a particular problem and asking about a
way to implement it, rather than describing the original problem itself.

What would be your real use case for such "partial" clone?
To put it another way: what do you want to achieve?

Are you seeking for minimizing the amount of bytes to be downloaded?
If yes, do you still need the whole history of changes touching the
Win32 subtree or are fine with just the latest slice of them?
Do you need to continue developing on that snapshot and pushing your
changes back or you just want to download that stuff for using it (say,
building) so your cloning operation would be a one-off gig?

Please consider all this stuff carefully before replying.
