+Subject: [PATCH] PHP 7.3 compatibility and bugfixes
+
+- Define new GC_ADDREF/DELREF/SET_REFCOUNT macros for older PHP versions and use them instead of direct GC reference counter access
+
+- Fixup all necessary 'long' type parameters to 'zend_long', PHP 7.3 makes it mandatory, also fixup some direct function implementations to accept the same
+
+- In php_zmq_recv(), zend_string_init() was wrongly called with third parameter as '1', marking new string with IS_STR_PERSISTENT, this caused heap corruption and/or segfaults with PHP 7.3 and could possibly cause other sorts of bugs under any 7.x version
+  With ZVAL_STRINGL macro, this last '1' parameter meant to copy the string and was seemingly erroneously moved to zend_string_init(). zend_string_init() copies string by default, and last parameter has totally different meaning here
+
+- In poll(), flag ZVAL separation on passed arrays (PHP 7.3 makes it mandatory)
+
+- Test 19 (exception on connect callback with forced reference parameter): skip on PHP 7.1 and higher, PHP >= 7.1 started to fallback to passing argument by value instead of failing
+
+- Test 21 (warning generation from callback): it is ok, but PHP 7.3 uses 'int' instead of 'integer' for constants, so allow any word in place of the word 'integer'
+
