This PyOpenSSL won't compile against newer OpenSSL versions

[df-cryptostorm]

On CentOS 6.5 using OpenSSL 1.0.2a, I received this error when trying to compile pyOpenSSL with:
python setup.py install

OpenSSL/crypto/crl.c:6: error: static declaration of 'X509_REVOKED_dup' follows non-static declaration
/usr/include/openssl/x509.h:751: note: previous declaration of 'X509_REVOKED_dup' was here

Looks like later OpenSSL versions use an "X509_REVOKED_dup" already.
(See https://github.com/openssl/openssl/blob/master/include/openssl/x509.h)

The quick/lazy fix for me was to change all "X509_REVOKED_dup" to "X509_REVOKED_dupe" in OpenSSL/crypto/crl.c. I.e.,

sed -e's/X509_REVOKED_dup/X509_REVOKED_dupe/g' -i OpenSSL/crypto/crl.c
(while in pyOpenSSL-0.13)

Thanks for reporting this! Will fix it over this weekend.

FYI upgrading to pyOpenSSL >= 0.14 should fix this, see pyca/pyopenssl#276

Changed all "X509_REVOKED_dup" to "X509_REVOKED_dupe". Should work fine now.
