So I have submitted it: [http://xcas.e.ujf-
grenoble.fr/XCAS/viewtopic.php?f=4&t=1539]
The current status is that the patch is included in the upstream source
1.1.2 08-Oct-2014 16:45. (it is not a frozen source)

Well it was just a rough estimate because one year ago I didn't knew any
giac functions using pari that were not already in sage via pari. But now
I saw some solve and resultant are also using pari, and I believe that it
will increase.
