Thank you for this information, Paul, I had no idea that printf and the va_ functions were 'open source'. Microsoft usually likes to hide their stuff :P
It depends on how you installed your VC++ compiler. There are options of whether you want the RTL source or not. If you don't see the RTL source code, then either you have a downgraded version of the compiler which doesn't give you the RTL source, or you didn't choose the option to install the RTL source code.
