  New Revision: 65906

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=65906

  Log:
    errno.h must be included after config.h because config.h might define
    _REENTRANT, _THREAD_SAFE, etc., which affect how errno is defined
    on some architectures
    
    * ext/openssl/ossl.h: include errno.h after ruby.h
    
    * include/ruby/io.h: include errno.h after ruby/config.h
