Yes, I know. But I need to set the defines only when I use the Code Analysis, not when I compile the project, because the compiler does this automatically when I specify the processor type on the command-line (which is required).
So I don't want a permanent define, I want it only when Code Analysis is looking at the source code.

So I want something like this:

#ifdef CODAN_IS_RUNNING
#define PROCESSOR_TYPE
#endif

So when Code Analysis is not running, there is to conflict between this define action and the one the compiler itself is doing.
