GPGME support for PGP2 option?

I would like to explain my question more clearly.

I have GPG 1.4.7, and I installed the extension module that support IDEA key
for PGP 2.6.x compatibility.
When I receive an encrypted message from PGP 2.6, the GPG can decrypt it
When I use GPG command line to create a message to send to PGP 2.6 users, I
can use the option --pgp2 to encrypt a message that PGP can decrypt.

However, if I write a program using GPGME API and want to encrypt a message
to send to PGP 2.6, what is the parameter that is equivalent to the --pgp2
option ?
