The third update of Emacs 24.3 Mac port 4.x is now available from


As far as I tested, compilation with "clang -O4", which includes
link-time optimization, seems to work again for x86_64 with the latest
version of clang that can be installed by Xcode 5.0 on OS X 10.8.  You
can optionally try ARC (Automatic Reference Counting) by specifying
CC='clang -fobjc-arc' on configure.

** Fixed bugs

*** Invocation via "Login Items" or "Resume" does not respect PATH
setting in ~/.MacOSX/environment.plist on OS X 10.7 and earlier.
Note: OS X 10.8 does not use ~/.MacOSX/environment.plist anyway.

*** Spotlight in Help menu is not installed on Mac OS X 10.5 if
language setting is other than English.

*** Closing a window causes crash if compiled with ARC.
This primarily happens with the latest clang Apple LLVM version 5.0,
but also with earlier versions if the memory leak below is fixed.

*** Memory leaks with ARC on clang Apple LLVM version 4.2 (possibly
compiler bug).

** Improvements

*** Try built-in libxml2 on OS X 10.8 as a fallback.
