And the same change was previously rejected as well, with the same 
reasoning:

http://mailman.nginx.org/pipermail/nginx/2012-August/034889.html

Now we are moving away from OpenSSL 0.9.7 support, targeting 
OpenSSL 0.9.8 as a minimum supported version.

This patch effectively limits minimum OpenSSL version nginx is 
able to build to OpenSSL 0.9.7e, though older versions are still 
supported in the code.  Support for older versions is likely to be 
removed from the code in the upcoming nginx versions.
