SSL_OP_SINGLE_ECDH_USE has been defined in OpenSSL's ssl/ssl.h since
draft ECC support was first committed on 9 Aug 2002[1]. OpenSSL's
CHANGES file states that draft ECC support was added between
openssl-0.9.7 and openssl-0.9.8. OpenSSL has also been defining
OPENSSL_NO_ECDH in the build script since 30 Jan 2009[2]. All releases
in the openssl-0.9.8 series and higher should therefore have both
SSL_OP_SINGLE_ECDH_USE and OPENSSL_NO_ECDH defined.

Would I be correct to assume that Solaris 10 is bundling OpenSSL
<=0.9.7?
