Sometimes you really need to know what defines your compiler has on by default. I had no idea how
to do this with Visual Studio so I dug in. Here is how to do it.
Open up a VS command prompt, pick the appropriate prompt x86, x64 etc.
enter the following:
| > echo int main(){} > test.cpp
> cl.exe /PD /Zc:preprocessor test.cpp
|
You should see output similar to the following:

I turned this in to a simple batchfile
Hope this helps.
