V505 The 'alloca' function is used inside the loop. This can quickly overflow
     stack.
V745 A 'wchar_t *' type string is incorrectly converted to 'BSTR' type string.
     Consider using 'SysAllocString' function.
V768 The variable 'mnVersion' is of enum type. It is odd that it is used as a
     variable of a Boolean-type.
