After checking out the the fresh one, removing all the env variables and set it manually on the command line it compiles now without any trouble. The "> nul" was an absolute false clue from me but was kind of reproducible (-: *stupid_me* I apologies for the noise! It seems you were absolute right. Taking a really good look at the env variables solved all the build issues (-; The env settings were now: set PATH=%PATH%;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE;C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin;C:\GnuWin32\bin\ set INCLUDE=%INCLUDE%;C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Include;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include set LIB=%LIB%;C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib;C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\lib And afterwards there is no complain from any build script (-: Thanks again Park for your great help!
