Hi Arne,
I believe I fixed the issues that you mentioned in your review of the
patch for wolfSSL. I have sent a new patch tested on the latest master
branch on OpenVPN along with the version of wolfSSL found in this pull
request: https://github.com/wolfSSL/wolfssl/pull/3697 .
Unfortunatel,y I am still not able to compile that branch on
macOS/clang. It seem wolfssl uses -Werror and this breaks it. On a quick
check I also don't see an option to disable this behaviour in configure.
The master branch compiles but that doesn't work for OpenVPN.
