Thank you Markus and Wolf. I did not think to search in
grass-source/vector directory. It also makes sense now why it's not
compiled by default.

I am fighting to get something on the screen. I have the impression that
it works but I can't find the proper size (in metres)?

Would this be considered as an extra feature? Estimating a default size?

Excuse my ignorance if this is something extremely difficult or
impossible.
