* Andrew Suffield:
Here's the snarly bit:
Take a copy of curl, not built with ssl support. Build your GPLed
application, linking it to this curl. There should unarguably be no
problems here - everything involved is GPL-compatible.
Now, go and build a copy of curl that is linked to openssl. Install
that one instead, not touching the GPLed application.
What just happened? What is going on here and where is the boundary?
Probably distribution. If you distribute just the OpenSSL of curl
version, it's rather clear that you intent that all applications
linking against curl also link against OpenSSL.
