Hi. I'm attaching a new version of the port to the Haiku operating
system, which should be complete enough for general usage. The patch
should apply cleanly to a current repository check-out.
I would appreciate it for someone using Haiku as his daily driver to
take his time to try this, and for someone to take the time to glance
over the patch and tell me if I missed something. If it doesn't build
for you or crashes, please let me know.
I'm also not sure Emacs with this patch will still build on a few
platforms I can't test, namely macOS and MS-Windows. It would be nice
for someone with a Macintosh to verify that Emacs still builds with this
patch in place, and inform me of any issues so I can rectify them.
Changes and known problems have been documented in NEWS, MACHINES, and
PROBLEMS where appropriate, and I think the updates to the Lisp
reference manual are complete, and that no updates to the other manuals
are necessitated by the scope of the changes currently present. If
nobody finds anything missing, I hope that it will be appropriate to
mark the changes as documented in NEWS.
It would also be nice to expedite the paperwork; I haven't heard
anything from Craig Topham in a while.
This is probably too late to make it into Emacs 28, but perhaps I'm
being overly pessimistic?
The patch also includes a copy of the X Pixmap Library (which is free
software) with modifications made by me, as the libXpm shipped by Haiku
has a hard dependency on a running X server. Because the port is built
as part of Emacs, there are probably some copyright related issues to
work out. If there are any, how should I proceed with sorting them out?
Thanks.

+libXpm - X Pixmap (XPM) image file format library
+-------------------------------------------------
+
+This directory contains a port of the X Pixmap library to Haiku; on
+other platforms, Emacs uses the system libXpm.
+
+Almost everything neccessary is included in this directory, with the
+notable exception of an implementation of everything in simx.h, which
+is actually in the main Emacs source folder under the name
+haiku_simx.c.

+ * other client. (Note: X _should_ allow clients to check if a
+ * particular color is Read/Write, but it doesn't! :-( ). We

+ * the next closest color, and so on, until no more colors are
+ * within closeness of the target. If we knew that the colormap
+ * had changed, we could skip this sequence.
+ *
+ * If _none_ of the colors within closeness of the target can be
+ * allocated, then we can finally be pretty sure that the colormap
+ * has actually changed. In this case we try to allocate the
+ * original color (again), then try the closecolor stuff
+ * (again)...
+ *
+ * In theory it would be possible for an infinite loop to occur if
+ * another process kept changing the colormap every time we sorted
+ * it, so we set a maximum on the number of iterations. After this
+ * many tries, we use XGrabServer() to ensure that the colormap
+ * remains unchanged.
+ *
+ * This approach gives particularly bad worst case performance -
+ * as many as <MaximumIterations> colormap reads and sorts may be
+ * needed, and as many as <MaximumIterations> * <ColormapSize>
+ * attempted allocations may fail. On an 8-bit system, this means
+ * as many as 3 colormap reads, 3 sorts and 768 failed allocations
+ * per execution of this code! Luckily, my experiments show that
+ * in general use in a typical 8-bit color environment only about
+ * 1 in every 10000 allocations fails to succeed in the fastest
+ * possible time. So virtually every time what actually happens is
+ * a single sort followed by a successful allocate. The very first
+ * allocation also costs a colormap read, but no further reads are

+ On 32-bit Haiku it is required that the newer GCC 8 be used, instead
+ of the legacy GCC 2 used by default. This can be achieved by
+ invoking configure inside a shell launched by the 'setarch' program
+ invoked as 'setarch x86'.
+
+ When building with packages discovered through pkg-config, such as
+ libpng, on a GCC 2/GCC 8 hybrid system, simply evaluating 'setarch
+ x86' is insufficient to ensure that all required libraries are found
+ at their correct locations. To avoid this problem, set the
+ environment variable 'PKG_CONFIG_PATH' to the GCC 8 pkg-config
+ directory at '/system/develop/lib/x86/pkgconfig/' before configuring
+ Emacs.
+
+ If GCC complains about not being able to resolve symbols such as
+ "BHandler::LockLooper", you are almost certainly experiencing this
+ problem.
+
+ Haiku running on non-x86 systems has not been tested. It is
+ anticipated that Haiku running on big-endian systems will experience
+ problems when Emacs is built with Haiku windowing support, but there
+ doesn't seem to be any reliable way to get Haiku running on a
+ big-endian system at present.
+
+ The earliest release of Haiku that will successfully compile Emacs
+ is R1/Beta2. For windowing support, R1/Beta3 or later is required.

You might want to have a look at how the NS port deals with XPMs, see
image.c:4714.

Thanks. I don't see anything notable at that location, or around it, so
could you please explain in more detail? It would be nice to use Haiku
libXpm instead of shipping a modified copy.

Basically Macs don't come with libXpm, so there is code in image.c to
support xpm's directly. If libXpm is available then I believe it will
use it, but it means it's not a requirement.
Search for this comment:
/* XPM support functions for NS where libxpm is not available, and for
Cairo. Only XPM version 3 (without any extensions) is supported. */
