   a. zend_set_memory_limit() now takes the TSRMLS_CC macro as its last argument
+  e. New data types
+     String length
+	String lengths do no more depend on the firm 'int' datatype. The replacement
+	is a platform dependent size_t datatype. The string length in zval is no more
+	int but php_size_t.
+	String length is defined as zend_size_t inside Zend and aliased as php_size_t
+	anywhere else. The inclusion of php.h is necessary.
+     Integer types
+	Integers do no more depend on the firm 'long' type. Instead a platform
+	dependent integer type is used. That datatype is defined dynamically to
+	guarantee the consistent 64 bit support. The zval field representing user
+	land integer it bound to php_int_t.
+	Signed integer is defined as zend_int_t, unsigned integer as zend_uint_t
+	inside Zend. Both are aliased as php_int_t and php_uint_t anywhere else,
+	respectively. The inclusion of php.h is necessary.
+     Other datatypes
+	zend_off_t  - portable off_t analogue
+	zend_stat_t - portable 'struct stat' analogue
+	These datatypes are declared to be portable across platforms. Thus, direct
+	usage of the functions like fseek, stat, etc. as well as direct usage of
+	off_t and struct stat is strongly not recommended. Instead the portable
+	macros should be used.
+	zend_fseek - portable fseek equivalent
+	zend_ftell - portable ftell equivalent
+	zend_lseek - portable lseek equivalent
+	zend_fstat - portable fstat equivalent
+	zend_stat  - portable stat equivalent
