Cyrus SASL conflicts with OpenSSL

[Artem Harutyunyan]

Hi,

I am writing a new mechanism plugin, in which I need 
to use OpenSSL functions. When I am including OpenSSL 
headers (namely 'openssl/pem.h') among with Cyrus SASL 
headers ('plugin_common.h', 'saslplug.h' etc) I am getting the 
following compilation error:

The problem is that in 'openssl/md5.h' there is a definition of 
structure called MD5_CTX which conflicts with definition of 
MD5_CTX from 'cyrus-sasl-2.1.21/include/md5.h'.  

How this conflict can be resolved ?

Thanks in advance for reply,
Artem.
