compatibility mode.
* g10/misc.c (idea_cipher_warn): Remove.  Also remove all callers.
* g10/seckey-cert.c (do_check): Remove emitting of STATUS_RSA_OR_IDEA.

--

To keep the number of actually used algorithms low, we support IDEA
only in a basically read-only way (unless --pgp2 is used during key
generation).  It does not make sense to suggest the use of this old 64
bit blocksize algorithm.  However, there is old data available where
it might be helpful to have IDEA available.

%%name: GnuPG
%%short-description: Complete implementation of the OpenPGP Internet standard.
%%full-description: A complete and free replacement for PGP. The
program does not use any patented algorithms, and can be used as a
filter program. Can handle all OpenPGP messages and messages generated
by PGP 5.0 and later.
Supports ElGamal (signature and encrytion), DSA, AES, 3DES, Blowfish,
Twofish, CAST5, IDEA, MD5, SHA-1, RIPE-MD-160, and has language
support for sixteen different languages.
It is believed to be fully OpenPGP (as defined in RFC2440) conform,
and has integrated support for HKP keyservers. There are a lot of
useful extra features like anonymous message recipients.
