But NOT useless for detecting potential problems with *other* platforms.

So *testing* it using /Za isn't useless, for the tiny cost (and admittedly
modest likelihood of finding problems).

If /Za isn't possible, then it warns that there is a significant risk it won't
work on other platforms.

(But not *certain* to fail because the coding may carefully cope with multiple
platforms - like Boost.Filesystem).
