cyrus-imap25 compilation problems

[Andrea Venturoli]

Hello.

Compiling cyrus-imap25 on a 9.3/amd64 box of mine fails with:

> lib/imclient.c: In function 'tls_init_clientengine':
> lib/imclient.c:1644: error: 'SSL_OP_NO_COMPRESSION' undeclared (first use in this function)
> lib/imclient.c:1644: error: (Each undeclared identifier is reported only once
> lib/imclient.c:1644: error: for each function it appears in.)

Full log attached.

The same compiles on 10.1.

Any hint?

  bye & Thanks
