[Individual|Corporate] Contributor License Agreement

[Frederic Bonnard <frediz@linux.vnet.ibm.com>]

Hi everybody,
I'm wondering if an agreement meets the DFSG during the packaging
process of a library called libvecpf. It's under GPLv2.1+ but there are
2 additional files which are agreements.
Depending if you are an individual contributor or a corporate one :
- https://github.com/Libvecpf/libvecpf/blob/master/ICLA.txt
- https://github.com/Libvecpf/libvecpf/blob/master/CCLA.txt

I see amongst some problems with :
- contributor must fill, sign and send the agreement
- reveal his identity
- notify the Libvecpf Maintainer of any facts or circumstances of which You
  become aware that would make these representations inaccurate in any respect.

Can anybody confirm those points ? (maybe others ?)
If so, what could be changed to make it DFSG compliant ?
Thanks for any help.
Regards,

F.
