Re: Emacs Mac port

[YAMAMOTO Mitsuharu]

The first update of the Mac port based on Emacs 27.2 is now available
from

  ftp://ftp.math.s.chiba-u.ac.jp/emacs/emacs-27.2-mac-8.3.tar.gz

and Git repository is also available at

  https://bitbucket.org/mituharu/emacs-mac.git

If you build from the repository on M1 Mac with newer autoconf, then
you will need to do "git restore build-aux" after "./autogen.sh".

** Fixed bugs

*** Frame may become blank with rapid repetitive zoomings.

*** Frame may become blank with isearch if the executable is compiled
with SDK 10.15 or earlier and runs on some later versions of macOS 11,
or NSWindowSupportsAutomaticInlineTitle is set to NO on macOS 11.
Note: NSWindowSupportsAutomaticInlineTitle has no effect on macOS 12.

** Improvements

*** Incorporate process creation code that uses posix_spawn.
This is a workaround for slow process creation on macOS 12, where
vfork is declared deprecated and mostly identical to fork.  The new
process creation code is incorporated from the posix-spawn-no-gnulib
branch upstream, and enabled by default on macOS 10.15 and later.  If
you have a problem with this new code, then set the variable
darwin-try-posix-spawn to nil so as to revert to the original one.

*** Avoid copying whole bitmap in application-side double buffering.

*** Update emoji data to version 14.0.

*** Live resize transition animation takes account of tab bar area.
