Please do not merge yet. This is not covering all fixes we did.

Yes, and actually I want to test the current master branch on Solaris 10, see what fails. I'll update the PR in the coming days.

Oops... just saw the message .. sorry. Just do another PR with the rest of changes if any come up. I will hold on the release ..

[mosabua]

Also .. the fixes in that revision dont apply anymore since the script works a bit different now..

[rpelisse]

@mosabua Yes, I saw that will porting the change. Here is what I am going to do before doing anymore PR. I'm going to run the current master (even before this PR was merged) on Solaris - see if it also fails. If so, i'll add this PR, and if needed I'll also add the changes mentioned above by @ppalaga .

I'll let you know what it comes out of it.
