I suggest Emacs support for OS X 10.4 be explicitly dropped.
The OS itself is unsupported for 5 years.

There are 6 open Emacs bugs about it, all from a single person.
Half of them say it doesn't build, or crashes immediately.
All but one are unanswered, which suggests we already dropped it implicitly.

Yes.  The general guideline in GNU packages is that when a platform's supplier 
no longer supports the platform, the GNU package doesn't need to support it 
either.  This is a reasonable guideline for Emacs too, e.g., our recent dropping 
support for IRIX 6.5 after SGI stopped support.  Since Apple has also dropped 
support for OS X 10.5 and 10.6, we should probably drop support for these 
versions as well.

Hah, oh man, good luck trying to get Emacs to drop Windows 9x etc... ;)

FWIW, that was what I was aiming for when merging macfont.c.  So I totally agree
and planned to do this at some unknown future time (after the release probably).

I don't think anyone hacking on the ns-code has 10.4 available.

It's just a guideline, not an ironclad rule.  If a developer is amused by 
keeping Emacs working on an old platform and if this doesn't get in the way of 
the rest of us, it's fine.  But the default should be to drop junk that's 
present only for obsolete and unsupported platforms.  For example, there's no 
longer any need to clutter the code with support for K&R C.

I would not want to drop 10.6, it still has significant usage, 18% in March according to:

http://www.macrumors.com/2014/03/27/os-x-mavericks-adoption-50/

Also, I have a 10.6 machine.  26.1 would perhaps be reasonable.

Old PowerPC Macs cannot run later versions of the OS than 10.5. Perhaps that is why, according to the same page, about 3% of Macs are on that version.

I am not saying that support for 10.5 shouldn't be dropped too, just mentioning this as a possibly relevant fact.

We should drop PowerPC also.  It has been unsupported in practice for years.

Please note that there are still quite some 10.6.8 installations
around since it was the last version of Mac OS X to include Rosetta.

And there’s the soon-to-be-released Emacs 24.4 that will work just fine on them. :-)

I doubt that people running such an old operating system have any illusions about being able to run all the latest and greatest software.

Jan, who does the work, and is therefore the only person whose opinion
really matters, has already said he will keep 10.6.

Hello.

Trunk now requires 10.6.  Older code is removed.  macfont.m is always used on COCOA,
nsfont.m only on GNUStep.  PowerPC unexec code is gone.

Thanks for doing all that.  I also squashed a few stray mentions of older 
versions in the documentation.  One little thing: the 'clear' method in nsmenu.m 
has a pre-10.6 hack; could it be simplified as per the attached?

Go ahead.  I will check on some OSX versions to be sure.  Just because the comment says 10.5 does not make it certain.  I don't recognize that particular hack.

It seems like the OS X version is only tested for --with-ns builds.
Should it not also be tested for any build on OS X (X, no-X)?

Also this is the kind of thing to mention in NEWS.

I can move it.  I puit it there because of similarity to the IRIX message.

I don't think so.  After all, if you are building for X or no toolkit, it is basically just UNIX with an unexec that works on Intel.  I don't think that we should prevent configurations that we in principle support (X, no-X, unexmacosx.c).  A check for PowerPC might be in order though as we don't support that.

I could add that, but I don't have any PowerPC to test it on.

Oh, but all the other points still apply:

OS X 10.4 itself is unsupported for 5+ years.
No Emacs developer has it to test on.
All the bug reports about it come from one person (who seems to be doing
an "explore the compilation parameter space" thing rather than actually
wanting to use it).
All the bug reports are about PPC;
  http://debbugs.gnu.org/cgi/pkgreport.cgi?include=subject%3A10.4;package=emacs
 (whether this means it is working fine on non-ppc, I have no data for! :) )

So personally I see no value to pretending it is still supported, and
think it might as well be explicitly dropped.

> A check for PowerPC might be in order though as we don't support that.

Should be easy?

I have to do some other test, because the test relies on Cocoa dev environment being present.
Stand by.

Hello.

I have added a test to configure.  But I was wondering about crosscompiling.  We really do not support that, do we?

IIUC, I don't think you need to call uname -r again, because that
information is already in $canonical. build-aux/config.guess does:

  UNAME_RELEASE=`(uname -r) 2>/dev/null` || UNAME_RELEASE=unknown

and then

  ${UNAME_PROCESSOR}-apple-darwin${UNAME_RELEASE}

So I think it can just be merged into the main $canonical "unported"
test (see eg handling of sunos versions).

IIRC, we don't support that at all, anywhere.

Hi Glenn,

I noticed when it stopped working (a display problem) and filed a bug.
It's fine if you stop supporting 10.4. I spent way too many hours on
that Mac anyway. I have decided to shelve it.
