axTLS is naughty when it defines symbols (like bool) out of its name space. That's an axTLS bug, not a curl bug.

Regarding ssl_client_new it sounds as if they've changed their API?

[boostiewj]

@bagder yes.they've changed their API.add some features.That's an axTLS bug for bool,but refuse to submit bug

[bagder]

1. axTLS refuses to accept bug reports from users
2. I still can't build axTLS, make just returns with errors and during the minutes I looked into it I couldn't figure out why

So we can't report the axTLS bug and I can't work on fixing the libcurl side of things.

[bagder]

I got a config file from @dfandrich and using that I could build axTLS 2.1.2.

1. Remove the bool typedef from the axTLS public header. It shouldn't be there.
2. Apply my patch. It adapts to the new API for ssl_client_new and fixes a bug with session IDs that I noticed.

Does anyone think it is worth keeping support for the older axTLS API?

[cryptocamtech]

I'll remove the typedef char bool on the next build. But the API has changed due to SNI functionality being added. Looks like curl supports it: http://stackoverflow.com/questions/12941703/use-curl-with-sni-server-name-indication#12942331.

[bagder]

Of course curl supports SNI, it would be hard to function on the Internet without it! =) But quite apparently it does not do SNI with axTLS yet since we can't build with a axTLS version using the modified API.

I'm leaning towards just stating that we no longer build with older axTLS versions.
