I guess I was confused by Corinna's original message. I thought she was
reporting a problem with upx and .tls, and another problem with dep +
.tls. But my tests show that everything works fine -- on an XP box
without DEP. So, is the problem is *only* dep + .tls?
(My test results below, for the record...)

I just built setup.exe from today's CVS using
binutils 2.19.51-1
mingw-runtime 3.18-1
gcc-core 3.4.4-999
cygwin 1.7.1-1
upx 3.01-1
and the uncompressed binary worked fine. It does have a .tls section:
$ objdump -p build/setup.exe
setup.exe: file format pei-i386
Characteristics 0x107
relocations stripped
executable
line numbers stripped
32 bit words
...

found it)]

Entry f 00000000 00000000 Reserved
After copying the binary over to my deployment area, and manually
running upx:
$ ls -l build/setup.exe
-rwxrwxr-x 1 15319826 2010-03-17 15:27 build/setup.exe
$ ls -l deploy/setup.exe
-rwxr-xr-x 1 4235538 2010-03-17 15:33 deploy/setup.exe
And it worked just fine. I built using -O2 -g, but did not explicitly
strip the debug symbols.
Trying that....
$ cp build/setup.exe ./setup.exe
$ strip ./setup.exe
$ ls -l ./setup.exe
-rwxrwxr-x 1 1678848 2010-03-17 16:09 setup.exe
$ objdump -p ./setup.exe
./setup.exe: file format pei-i386
Characteristics 0x30f
relocations stripped
executable
line numbers stripped
symbols stripped
32 bit words
debugging information removed
...
Entry 9 00000000 00000000 Thread Storage Directory [.tls]
....and the the stripped, but uncompressed, version worked just fine,
too. Now, stripped AND uncompressed:
$ upx ./setup.exe
$ ls -l ./setup.exe
-rwxr-xr-x 1 655360 2010-03-17 16:10 setup.exe
....which also worked fine.
