Re: Compiling zsh-4.0.2 on Mac OS X

[Oliver Kiddle <okiddle@yahoo.co.uk>]

Sourceforge have just added a couple of MacOS X machines to the compile
farm so it is now easier to work out what is happening here.

Yes, that seems to work so I'll commit that change (both branches).

This appears to be a bug in chmod as far as I can tell. chmod +t simply
doesn't work even though the man page says it should and the numeric
equivalent does. Changing the three chmods to one numeric one allows it
to set the sticky bit and the test to then work. If this change causes
problems on other platforms, we can use a $OSTYPE check. Anyone know
where I should report Darwin bugs to?

As Andrej pointed out the remaining failures were due to the lack of
modules such as zpty. Dynamic module loading doesn't work on MacOS X
because it uses Mach-O instead of ELF binaries which the dl* functions
are based around. Darwin uses some different NeXT based system instead
apparently. Perhaps the tests should better handle missing modules by
printing a succinct message and skipping the affected tests.

Anyway, I rebuilt a static zsh with the necessary extra modules. All
tests up until Y03 then passed successfully. Y03 hangs indefintely.
>From the verbose output, it is hanging on the `a and b' test. I'm not
very familiar with these completion tests so I've not looked into this
in detail.

The patch below also adds a mention of Darwin in Etc/MACHINES: it
should build `out-of-the-box' now though I expect there to be other
problems.
