Description:
------------
Source won't compile. 
First, it complains about not finding fourd.h. I fixed that by adding 
-I./lib4d_sql to Makefile, after configuration. 
Then an error is thrown (see Actual result below). After replacing function_entry 
with zend_function_entry (see patch below), it compiled successfully. 


Expected result:
----------------
Compile source 

Actual result:
--------------
