Right, .. now that you mention it, we have a patch like that in
Debian since long:

Not good, why not check only the first three items, that should be
fine. In Debian we do since long:
@@ -551,7 +551,7 @@
 
     /* make sure header and library version are consistent */
     const char* version = zlibVersion();
-    if (strncmp(version, ZLIB_VERSION, 5))
+    if (strncmp(version, ZLIB_VERSION, 3))
     {
         lua_pushfstring(L, "zlib library version does not match - header: %s, library: %s", ZLIB_VERSION, version);
         lua_error(L);


Best wishes
