Hi, first post to list.

LibreSSL user.

PHP 7.1.0RC5 just needs one minor patch to work with LibreSSL, attached

Justification -

X509_get_signature_nid() was introduced in OpenSSL 1.0.2 but LibreSSL 
fork is prior to that.

However (and I don't like this) LibreSSL uses a `OPENSSL_VERSION_NUMBER` 
defined as 0x20000000L

So have to check for presence of LIBRESSL_VERSION_NUMBER when using 
functions introduced to OpenSSL after the fork (1.0.1h I think)

Tested building against LibreSSL 2.4.3 on a CentOS 7 system (where 
OpenSSL has been completely removed) - 7.1.0RC5 compiles and works with 
that line changed.
