Sorry, but you proposed to break them completely:

Wasn't your statement meaning that if somebody's compiler is "broken" (does
not support *nonstandard* stack alignment option), he is screwed and
deserves it?

I hope it was just a misunderstanding. But I remember mingw getting blamed for
the stack alignment issues at the very same time (well, mingw at least claimed
to support that option but did it wrong, or I'm mistaken again?).
