The HAVE_CRYPTO_CLEANUP_ALL_EX_DATA macro is set by autoconf whenever it's
available in the OpenSSL lib. Since Windows' config.h isn't created
automatically, it will probably have to be added manually. Maybe it should
be set by default in config-win32.h and a note added to the INSTALL file to
comment it out when using an old OpenSSL.
