I've installed Visual Studio C++ Express 2012 and want to use it's compiler with Code::Blocks. Starting `cl.exe` does not work (missing *mspdb100.dll*) until I run `vcvars32.bat`, but that does only hold on for the current session in the Command-line. The same applies to compiling with Code::Blocks. 

**How can I make it run the `vcvars32.bat` before compiling?**
