I don't see how the flag actually could help unless you were developing only on MSVC and then trying to port to other platforms.
But I think this is exactly what is true for many developers, so the earlier the MS- only users get warning that they are in MS-only-land the better. I had hoped that /Za would achieve this.
So unless there are other views, I propose to change the 'Dealing with warnings guidelines' to warn that the option is 'definitely dodgy'. (mainly by a link to this helpful post).
Although /Za might help a MSVC-only-shop a little during development, loading and testing on the trunk remains the definitive test of portability.
I am moving towards Michael's viewpoint, but I'd like more views on this before I make a change.
In the absence of other views, I will change (when I can login ;-) the 'guidelines' page as above https://svn.boost.org/trac/boost/wiki/Guidelines/WarningsGuidelines including a reference to Stephen's informative and authoritative MSVC /Za summary at http://article.gmane.org/gmane.comp.lib.boost.devel/212186/ Paul --- Paul A.
