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
  symbol                             in file

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 ?
