[Haskell-cafe] License question

Hello, I am writing a port to F# of some haskell standard libraries. I would like to publish them under an open source license and mention the origin of the initial code. www.haskell.org is under the simple permissive license. Does this license also cover the souce code available from that site? Is there any restriction about the license I might choose? Thak you Regards jcm
