Topic: wolfSSL: configure: zlib check
I noticed that even though the wolfSSL can be compiled without zlib and has all the appropriate ifdef's in the code, the configure script doesn't allow that - it errors out if zlib is not found. Was there a reason for making it impossible to configure wolfSSL without zlib? If not, here's the simple patch to allow running configure with "--with-libz=no" option:

fiFor what it's worth, I needed embedded SSL, and I've been compiling wolfSSL for an embedded platform without zlib for a while with no issues.
