[boost] svn.boost.org has invalid ssl certifcate

Hi! Maybe this is only an issue with paranoid or misocnfigured firefox, but annoying anyway, since I change platforms very often. firefox reports: svn.boost.org uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer) Can this be fixed on the server side? best regards, Markus
