Re: /Za option

Tech-Archive recommends: Fix windows errors by optimizing your registry

I am not sure you read what I wrote : what I'm trying to find out is
what is left out and what gets in when you use /Za. Za is advertised to
disable MS extensions and is supposed to be used to check for
portability problems, and portability assumes - of course - you will
not be including any windows specific headers. To be more specific, I
expect the compilation of the following program to fail (note there are
no windows spec. hdrs ):

#include <iostream>
class __declspec(novtable) base
{
public:
virtual void beep() {}
};
class test : public base
{
public
void beep() {};
};
int main(void)
{
test *p = new test();
p->beep();
return (EXIT_SUCCESS);
}
