There is one other possibility, if you add the following code to the header file:
#define VA_SKIP_START
#define VA_SKIP_END
VA_SKIP_START
// problem code
VA_SKIP_END
and add the following to VA's StdAfx.h
#define VA_SKIP_START /*
#define VA_SKIP_END */
This might work, so long as the code you are blocking out does not contain any /* */ comment blocks.
