Trying to compile this on an old Solaris 10 machine and over and over
and over I see these strange things as Undefined symbols :
Undefined first referenced

Those look like strange C11 atomics. Are they really needed somewhere?
I see include/internal/refcount.h talks about C11 atomics and yet the
entire code base is supposed to be C90 clean. See section the OpenSSL
Coding Style policy :
https://www.openssl.org/policies/technical/coding-style.html
Chapter 14: Portability
To maximise portability the version of C defined in
ISO/IEC 9899:1990 should be used. This is more commonly
referred to as C90. ISO/IEC 9899:1999 (also known as C99) is
not supported on some platforms that OpenSSL is used on and
therefore should be avoided.
Perhaps I need to define OPENSSL_DEV_NO_ATOMICS ?
