		// When using /analyze (triggered with /define:ANALYZE on the vpc command line) we want to forcibly disable lots
		// of warnings.
		// warning C6308: 'realloc' might return null pointer, cause the original memory block to be leaked
		// warning C6255: _alloca indicates failure by raising a stack overflow exception. Consider using _malloca instead
		// warning C6387: 'argument 1' might be '0': this does not adhere to the specification for the function 'GetProcAddress'
		// warning C6309: Argument '1' is null: this does not adhere to function specification of 'GetProcAddress'
		// warning C6011: Dereferencing NULL pointer 'm_ppTestCases'
		// warning C6211: Leaking memory 'newKeyValue' due to an exception. Consider using a local catch block to clean up memory
		// These warnings are because /analyze doesn't like our use of constants, especially things like IsPC()
		// warning C6326: Potential comparison of a constant with another constant
		// warning C6239: (<non-zero constant> && <expression>) always evaluates to the result of <expression>. Did you intend to use the bitwise-and operator?
		// warning C6285: (<non-zero constant> || <non-zero constant>) is always a non-zero constant. Did you intend to use the bitwise-and operator?
		// warning C6237: (<zero> && <expression>) is always zero. <expression> is never evaluated and might have side effects
		// warning C6235: (<non-zero constant> || <expression>) is always a non-zero constant
		// warning C6240: (<expression> && <non-zero constant>) always evaluates to the result of <expression>. Did you intend to use the bitwise-and operator?
		// These warnings aren't really important:
		// warning C6323: Use of arithmetic operator on Boolean type(s)
		// /analyze doesn't like GCOMPILER_ASSERT's implementation of compile-time asserts
		// warning C6326: Potential comparison of a constant with another constant
		// warning C6335: Leaking process information handle 'pi.hThread'
		// warning C6320: Exception-filter expression is the constant EXCEPTION_EXECUTE_HANDLER. This might mask exceptions that were not intended to be handled
		// warning C6250: Calling 'VirtualFree' without the MEM_RELEASE flag might free memory but not address descriptors (VADs). This causes address space leaks
		// warning C6384: Dividing sizeof a pointer by another value
		// warning C6318: Ill-defined __try/__except: use of the constant EXCEPTION_CONTINUE_SEARCH -- bogus
		// warning C6322: Empty _except block

		// Set the stack size threshold to 100,000 to avoid noisy warnings on functions with modest stack usage
		// Note that /analyze for VS 2010 only works with the 32-bit compiler, but for VS 2012 it works on 64-bit
