mercurial on pythonce

Hi
I would like to use mercurial with pythonce on my pocketpc device, and 
was going to try making some gui for it. Unfortunately i was not able to 
compile its C parts. Can someone, please, point me to the place, where i 
can read about compiling C modules for pythonce, or give some advice on 
this.
Thanks.

P.S. using gcc on linux or VS windows here
