Hi everyone...
When compilling with Visual C++ 2005, it needs the file "mspdb80.dll" (don't ask me why...). With this version, I've got a message box from cl.exe (the compiler) saying that this file is missing. When switching back to SVN4261, everything is OK (I haven't got any nightlies between these two).
[EDIT]: I'm downloading others nightly to see which one introduces this effect...
