========================
1. Internal API changes
========================
a. php_sys_symlink() and php_sys_link() portability macros have been
added, which behave like POSIX's symlink() and link(), respectively, on
POSIX compliant systems and on Windows.
b. zend_lookup_class_ex() and zend_fetch_class_by_name() prototypes were
changed to accept optional lower-case class name as zend_string*,
instead of zval*.
========================
2. Build system changes
========================
a. Unix build system changes
- configure --help now also outputs --program-suffix and --program-prefix
information by using the Autoconf AC_ARG_PROGRAM macro.
- Obsolescent macro AC_FUNC_VPRINTF has been removed and the HAVE_VPRINTF
symbol is no longer defined since it is not needed on current systems.
b. Windows build system changes
========================
3. Module changes
========================
