Subject: [PATCH] fix libressl support
|
|
heirloom-mailx has two small issues when compiling against LibreSSL:
|
- RAND_egd is used (LibreSSL does not support RAND_egd)
|
Solution: "Guard" the code calling RAND_egd
|
|
- SSLv3_client_method function is used (LibreSSL does not support SSLv3)
|
Solution: "Guard" the code with #ifndef OPENSSL_NO_SSL3
|
