The French law (see http://web.cnam.fr/Network/Crypto/)
forbids the exportation, supply and use of cryptographic
devices without declaration (for authentification) and
authorization (for confidentiality). A new law will apply
in some months but will not change this.

Then I have removed the cryptographic code (which is from
freewares freely available in some parts of Europe) and
the calls to cryptographic functions with an "unifdef"
for IPSEC_AUTH and IPSEC_CRYPT cpp flags.

I have kept the copyright notices in the case someone
would like to rebuild the code...
