Deprecation warnings under XCode

I have no idea whether this should concern anyone, but my mac build of git shows

Isn't the warning a warning ;-)
I don't see this warnings because my openssl comes from 
/opt/local/include (Mac ports)
Does anybody know which new functions exist in Mac OS X versions >= 10.7  ?

 From [1]:

In addition to these APIs, a number of open source tools use OpenSSL  
for secure networking. If you use OpenSSL in your publicly shipping  
apps, you must provide your own copy of the OpenSSL libraries,  
preferably as part of your app bundle; the OpenSSL libraries that OS  
X provides are deprecated.

So using the version from Mac Ports is the right idea to avoid the  
problem.  You can always define NO_OPENSSL.  imap-send.c has a --curl  
option now. (Which presumably automatically becomes the default if you  
define NO_OPENSSL and not NO_CURL?)
