Description:
------------
compile failure under php-6.

may be more errors but I can't get past this one.

Reproduce code:
---------------
ext/rar/rar.cpp:
PHP_MINIT_FUNCTION(rar)
{
	zend_class_entry rar_class_entry;

	INIT_CLASS_ENTRY(rar_class_entry, "RarEntry", php_rar_class_functions);
	rar_class_entry_ptr = zend_register_internal_class(&rar_class_entry TSRMLS_CC);

Expected result:
----------------
compile without errors.

Actual result:
--------------
/php-src/ext/rar/rar.cpp: In function 'int zm_startup_rar(int, 
int)':
/php-src/ext/rar/rar.cpp:636: error: invalid conversion from 
'void*' to 'UChar*'

offending line:
	INIT_CLASS_ENTRY(rar_class_entry, "RarEntry", 
php_rar_class_functions);
