I think the build machine might have the hiccups.
When I check now, the 32-bit build succeeds, but a few language packs fail because '..\bin\Release\bin\restext.exe' failed to start.
but the restext.exe must be ok because the language packs before that error are build correctly.
The x64 build fails now because the TortoiseSVN32_static.dll and TortoiseStub32.dll are missing, however looking at the 32-bit build log those are properly built.
Let's wait a few days, maybe the hiccups go away.
