-Between PHP 4.0.6 and 4.1.0, the Zend module struct changed in a way
-that broke both source and binary compatibility.  If you are
-maintaining a third party extension, here's how to update it:
-
-If this was your old module entry:
-
-zend_module_entry foo_module_entry = {
-    "foo",                /* extension name */
-    foo_functions,        /* extension function list */
-    NULL,                 /* extension-wide startup function */
-    NULL,                 /* extension-wide shutdown function */
-    PHP_RINIT(foo),       /* per-request startup function */
-    PHP_RSHUTDOWN(foo),   /* per-request shutdown function */
-    PHP_MINFO(foo),       /* information function */
-    STANDARD_MODULE_PROPERTIES
-};
-
-Here's how it should look if you want your code to build with PHP
-4.1.0 and up:
-
-zend_module_entry foo_module_entry = {
-#if ZEND_MODULE_API_NO >= 20010901
-    STANDARD_MODULE_HEADER,
-#endif
-    "foo",                /* extension name */
-    foo_functions,        /* extension function list */
-    NULL,                 /* extension-wide startup function */
-    NULL,                 /* extension-wide shutdown function */
-    PHP_RINIT(foo),       /* per-request startup function */
-    PHP_RSHUTDOWN(foo),   /* per-request shutdown function */
-    PHP_MINFO(foo),       /* information function */
-#if ZEND_MODULE_API_NO >= 20010901
-    FOO_VERSION,          /* extension version number (string) */
-#endif
-    STANDARD_MODULE_PROPERTIES
-};
-
-If you don't care about source compatibility with earlier PHP releases
-than 4.1.0, you can drop the #if/#endif lines.
