Can someone please explain to me why you can't have #include statements within a #ifdef #else # endif conditional structure in Microsoft C++ ver. 6.0?
example:
#ifdef LEGACY_CODE
#include "first.h"
#include "second.h"
#else
#include "third.h"
#include "fourth.h"
#endif
The compiler gives the error 'fatal error C1020: unexpected #else'.
This is the first time I attempted to do this so I am not sure if this is just MS compilers or all C++ compilers in general.
I can't see anything wrong with what you have posted.
Maybe there is a problem in one of the other header files.
Hi
There is nothing wrong there. Please check out ur code one. It may be giving that problem due to some other bug.

Are the 4 header files in your project? If not that might be what is causing the error. I have used conditional assemblies like this with NO errors.

I'm pity to tell you I suppose your header file: first.h or second.h, maybe some nest error.
And, I can almost ensure that error is in second.h.
So, check the header file, to ensure it's no any error, just like:
#ifndef __second_h
#define __second_h
//...
#endif//__second_h
#endif//ERROR!
//END OF FILE
Notice that no matched #ifdef above it.
So, good lucky!
