Description:
------------
The extension fails to compile with undefined type ulong

I added a typedef to line 56 of solr_types.h and now it compiles:

--- solr_types.h.dist	2020-06-17 13:51:19.855753000 -0700
+++ solr_types.h	2020-06-16 16:32:27.191956000 -0700

 #include <libxml/tree.h>
 
 typedef unsigned char solr_bool;
+typedef unsigned long   ulong;            /* Short for unsigned long */
 
 #include "solr_string.h"


 


Test script:
---------------
Extract source
cd /usr/local/src/pecl-solr
phpize
./configure
make
make install

Expected result:
----------------
I expect the extension to compile and install

Actual result:
--------------
Fails because there is no typedef for ulong
