As I mentioned: (at least I hope I mentioned it...) it was a quick

ENGINE_set_default() should be called early in the program.

Perhaps some additional curl_easy_setopt() options:

   parameter: engine name
   load an ENGINE and set it to the data structures...
   calls ENGINE_set_default()
   like 1. but don't call ENGINE_set_default()
   (for second session...)
   parameter: pointer to an ENGINE
   sets this as ENGINE
   parameter: pointer to a memory area that will get the actual
   ENGINE pointer

And I am no member of the OpenSSL core team and I had only a quick look
curl. So please bear with me...

But now I don't find the reference...

Me too...

Some of these changes might be the result of a misunderstanding of
the curl interface on my side side...
Some of these changes were quick hacks...
