The next (and hopefully final) pretest for what will be the 24.4 release
of Emacs (the extensible text editor) is available at
ftp://alpha.gnu.org/gnu/emacs/pretest/emacs-24.3.94.tar.xz
Please give it as much testing as you can.
As always, if you encounter problems building or using Emacs,
send a report to bug-gnu-emacs@gnu.org with full details
(if possible, use M-x report-emacs-bug).
Thanks for helping to test Emacs.

I tested it on few systems, builds OK on all the followings (amd64, with only curses support, no X):
Debian 7.6
gNewSense 3.1 (based on Debian 6)
Ubuntu 14.04.1
Trisquel 6.0.1 (based on Ubuntu 12.04 LTS)
OpenSUSE 13.1
CentOS 6.5
CentOS 7
FreeBSD 10
FreeBSD 9.3
OpenBSD 5.5
NetBSD 6.1.4
DilOS 1.3.7 (OpenSolaris/Illumos-based)
GNU Hurd/Debian 0.5 (i386)
"./configure" fails on MINIX R3.3.0/i386, but MINIX is not officially supported.
On thing I noticed, is that "configure.ac" (and thus "./configure")
has the following statement (line 38):
srcdir="/${srcdir:0:1}${srcdir:2}"
I believe these are bash-specific variable expansions, not posix-compatible.
This appears in an MINGW-related "if" block, so I guess most of the time it is not encountered.
But in one instance, I got:
$ ./configure
./configure: 3564: Syntax error: Bad substitution

MinGW uses only Bash.

But other platforms may still try to parse (?) those lines, even if they
don't execute them. Presumably that explains:
>> But in one instance, I got:

So can you replace it with something portable, eg sed?

To find out if that's the case here, Assaf could run the configure
script again, with this patch applied:

The patch itself was not enough, because it still contains the offending lines.
However, I think I managed to reduce the case to this:
=== MINIX R3.3.0 ===
$ sh -c 'echo ${a:0:1}'
sh: Syntax error: Bad substitution
$ sh -c 'true && echo ${a:0:1}'
sh: Syntax error: Bad substitution
$ sh -c 'false && echo ${a:0:1}'
sh: Syntax error: Bad substitution
=== Debian 7.6 ===
$ dash -c 'echo ${a:0:1}'
dash: 1: Bad substitution
$ dash -c 'true && echo ${a:0:1}'
dash: 1: Bad substitution
$ dash -c 'false && echo ${a:0:1}'
(no error printed)
=== NetBSD 6.1.4 ====
$ sh -c 'echo ${a:0:1}'
sh: Syntax error: Bad substitution
$ sh -c 'true && echo ${a:0:1}'
sh: Syntax error: Bad substitution
$ sh -c 'false && echo ${a:0:1}'
sh: Syntax error: Bad substitution
but:
$ ksh -c 'echo ${a:0:1}'
ksh: : bad substitution
$ ksh -c 'true && echo ${a:0:1}'
ksh: : bad substitution
$ ksh -c 'false && echo ${a:0:1}'
(no error printed)
====
The "offending" system is MINIX R3.3.0 (which isn't officially supported).
It is supposed to be MINIX kernel + NetBSD user-space,
so I'm not quite sure why "./configure" on NetBSD works while on MINIX it doesn't.
(something to do with re-exec as "ksh" ? though MINIX does have "/bin/ksh" ).
In any case, I think the examples above demonstrate that MINIX's default shell does parse the shell statements regardless of execution or not, unlike 'dash' or 'ksh'.
I don't know if this is POSIX-compliant-behaviour or not.

Just to put things in perspective, even after fixing/avoiding this issue, emacs doesn't build on MINIX as-is,
so this issue shouldn't delay a release...

Of course, because I wanted to determine whether the error was
triggered (a) at parsing time (the shell parses more code than
strictly necessary) or (b) at execution time (some problem with the
test of $MSYSTEM, which provokes the unwanted execution of
MinGW-specific code).
(It seems now clear that the answer is "a". Thank you)

Unfortunately POSIX doesn't allow that construction, even in non-executed code,
so a strict shell is within its rights to reject it. I installed a simple and
localized workaround as emacs-24 bzr 117537.

Is there an HTTP URL for an MS Windows binary?
The general tar, dated Oct 01, is available by HTTP here:
http://alpha.gnu.org/gnu/emacs/pretest/
And that directory has a link for `windows/', which used to be
used for Windows pretest binaries. But everything there dates
from 2010. I think we should be finished with the April 2010
pretest by now. ;-)
