Thanks very much for all the responses. There is strong consensus for retaining support for some varieties of 0.9.8 and possibly some 0.9.7.
A new RFC, then, for trunk/2.3 and beyond: - support and build warning-free with OpenSSL >= 0.9.8 - support and build with OpenSSL >= 0.9.7a, albeit with (harmless) compiler warnings about argument const-ness all over the shop - drop support for OpenSSL < 0.9.7a - drop support for non-OpenSSL/derivatives of OpenSSL (I have tried this out and it seems perfectly feasible.) Regards, Joe
