Can confirm that upgrading from 1.33 to 1.35 has fixed this. There was a big overhaul in 1.34 which I'm about to read about...

2. Strange that you say that C:/autoexec.bat is native. I would say C:\autoexec.bat is but this is not where you get the error.
3. What is your compiler? With some, you need to compile with macro BOOST_WINDOWS_API.
