Mac OS X Patch for Emacs 21.1

[Andrew Choi]

The following message is a courtesy copy of an article
that has been posted to comp.emacs as well.

Here is a patch to Emacs 21.1 to allow it to build and run under Mac
OS X:

  http://www.cse.cuhk.edu.hk/~akochoi/emacs/macosx/emacs-21.1-2-mac.patch.gz

The instructions for applying it are contained in the file:

The GUI code is basically a Carbonized version of that in Emacs 21 for
Mac OS classic.  The Unix API of Mac OS X is used to implement
synchronous and asychronous subprocess support and networking support.
A new `unexec' for the Mach-O executable file format, written entirely
from scratch (src/unexmacosx.c), provides support for `dump-emacs'.
The autoconf/makefile mechanism is adopted so Emacs will built on Mac
OS X with the Developer Tools installed.

Note that although Emacs 21 is released software, this patch is alpha
software.  Please treat it as such.  I will continue to work on it
though.  Comments and contributions (code) are welcome!  I will work
on adding this patch to the CVS repository for the next release.

Have fun with it!
