[RFC] OpenSSL capability detection

[Amos Jeffries]

As you may be aware OpenSSL had some API changes which we dutifully 
wrote #if-#else conditional code for using the mechanisms provided by 
OpenSSL for the purpose.

Then somebody in Fedora or RHEL decided to back-port the functionality 
into their older OpenSSL version. This corrupted the Fedora 17 release 
for a short while, just long enough to corrupt the main RHEL 5.* and 6.* 
distributions, and it now seems to have spread into the CentOS 6.* 
distributions as well.

We are urgently needing somebody to write a ./configure-time test to 
detect these old corrupted OpenSSL packages which present 1.0.0d API 
functionality and AC_DEFINE a macro which can be added to the #if-#else 
conditionals such that they are built using the 1.0.0d+ API of OpenSSL.

Any takers?
