** Emacs has been ported to the Haiku operating system.
The configuration process should automatically detect and build for
Haiku. There is also an optional window-system port to Haiku, which
can be enabled by configuring Emacs with the option '--with-be-app',
which will require the Haiku Application Kit development headers and a
C++ compiler to be present on your system. If Emacs is not built with
the option '--with-be-app', the resulting Emacs will only run in
text-mode terminals.
To enable Cairo support, ensure that the Cairo and FreeType
development files are present on your system, and configure Emacs with
'--with-be-cairo'.
Unlike X, there is no compile-time option to enable or disable
double-buffering; it is always enabled. To disable it, change the
frame parameter 'inhibit-double-buffering' instead.

** Emacs can now be optionally built with the Cairo XCB backend.
Configure Emacs with the '--with-cairo-xcb' option to use the Cairo
XCB backend; the default is not to use it. This backend makes Emacs
moderately faster when running over X connections with high latency,
but is currently known to crash when Emacs repeatedly closes and opens
a display connection to the same terminal; this could happen, for
example, if you repeatedly visit files via emacsclient in a single
client frame, each time deleting the frame with 'C-x C-c'.
