GnuPG and PGP 5.0 compatibility problem

PGP 5.0 substantially predates RFC2440, the IETF standard which GnuPG  
implements.  In fact, GnuPG doesn't even have a PGP 5 compatibility  
mode.  (It has --pgp6, --pgp7 and --pgp8, but nothing for PGP 5.)

PGP 5.0 is very, _very_ out of date.  Please consider upgrading to  
something more recent and standards-conformant.

To me, this would cause me to doubt whether I wanted them to have my  
financial information at all.
