RE: [GD-Windows] Strict ANSI and <windows.h>

[Grills, J. <jg...@so...>]

And there was much sadness.  Here's some code from STLPort, but the problem
is more generalized:  

template <class _Tp, class _Alloc >
void _Deque_base<_Tp,_Alloc>::_M_create_nodes(_Tp** __nstart, _Tp**
__nfinish)
{
  _Tp** __cur;
  _STLP_TRY {
    for (__cur = __nstart; __cur < __nfinish; ++__cur)
      *__cur = _M_map_size.allocate(this->buffer_size());
  }
  _STLP_UNWIND(_M_destroy_nodes(__nstart, __cur));
}

Because of the if() clause, the compiler doesn't know that __cur is always
going to be initialized in debug builds, and generates a warning on the last
line in the function.  So, it's not a perfect solution, but it still may be
better than not having it.  I'll have fix the errors as I come across them
and decide if it is worth it or not...

Excellent!  This works exactly as I desire.  No compile warnings, and in the
release build the disassembly doesn't show any sign of the if(False()){} at
all.  Time to go throw this in the header file that's always included,
rebuild, and see how it works for the whole project.

Thank you very much.

Maybe something like this :

inline bool False(){ return false; }
#define for if(False()){} else for

You can also use a global extern variable instead of the inline function.
You can also use this in Debug builds only, if you fear it adds a "runtime
impact".
