Hi!
My understanding is that this is not entirely accurate. If OpenSSL is
part of the operating system, then there is no problem:
https://people.gnome.org/~markmc/openssl-and-the-gpl.html
https://www.openssl.org/docs/faq.html#LEGAL2
And no, I don't expect to change the license to spread OpenSSL instead
of GnuTLS to W32. That beast ought to be contained, not spread ;-).
Happy hacking!
Christian
