[Vala] Process.spawn_command_line_async; do nothing in windows

[gontzal <txasatonga gmail com>]

Hello!!

Using "Process.spawn_command_line_async" in vala (windows) give me an error.
When i use it with the instaled libraries it goes well, but if i use 
Tarnyk's ValaWinPKG's libraries for a portable app, don't work!.
I suposse that is the same problem he had with "GSettings" and 
"Filechooser". Isn't?
Any ideas?

Thanks Gontzal.
