Could this patch also be modified to apply to 4.1.2? It may be the issue
preventing me from doing Windows builds of that release.

icu supports building on Cygwin using Cygwin's make, but for some bizarre
reason AOO builds it with MSVC's nmake using makefiles generated by a Perl
script and even completely bypassing ./configure (makefile.mk has
CONFIGURE_ACTION+= $(PERL) ..$/..$/..$/..$/..$/createmak.pl
..$/..$/..$/..$/..$/createmak.cfg .). It could not have been easy to set
that up, nor does the nmake build parallelize at all, which is why icu
wastes 5 minutes building while using only a single thread, so you have to
wonder why it was done that way.
Building with mingw or building on any other platform does use ./configure
and GNU make instead, which explains why we only see this bug with MSVC.
Anyway I think I've hacked icu into working. In allinone.sln I've made
layoutex project depend on the i18n project containing icuin.lib, and the
Perl script should convert that dependency into the makefiles it creates.
So far icu has been rebuilt 10 times with this patch (attached), succeeding
every time, so please test it and see if it works for you as well.

I have already done some of this. The key difference between failing and
non-failing is whether layoutex is built early or later in the build. See
the attached files for sample build outputs.
I believe layoutex has a dependency on icuin.lib that is not properly
declared in the makefile etc., allowing layoutex to be built too soon. If
so, the best fix would be to declare the dependency, but I don't know
enough about the dmake and configuration stuff to make that change without
some study first.

The icu module has a complicated build with scripts generating
makefiles...
I am not sure what approach to even take debugging this, but some ideas
might be:
* make a copy of a main/icu[/wntmsci12.pro] directory that builds and a
copy of one that doesn't, then diff the files to see what's different
* compare build logs with it working and not working, to see what steps
differ (eg. build order of some files might be different)
* try and follow the makefile to understand the problem analytically; my
first try didn't get me far
* give up completely, and just hack it. Make a loop in build.pl that just
keeps cleaning and rebuilding the module. If it builds 50% of the time,
with 10 retries only 1 in 1024 builds will fail, with 20 retries only 1 in
2^20 will fail, etc. Something like this might already have been tried in
the past, as build.pl contains the following code which is only run on
Windows:
sub give_second_chance {
my $pid = shift;
# A malicious hack for mysterious windows problems - try 2 times
# to run dmake in the same directory if errors occurs
my $child_nick = $processes_hash{$pid};
$running_children{$folders_hashes{$child_nick}}--;
delete $processes_hash{$pid};
start_child($child_nick, $folders_hashes{$child_nick});
};

My next step is to try to get rid of the intermittent failure of the icu
