Actually, my long experience is that it takes more than 2; but at, say,
4 systems (both byte orders, both 32 and 64 bits) you get most of them.
More important at that point is getting better compiler coverage; gcc
and friends is *not* the only compiler suite in the world, and different
compilers uncover a different spectrum of bugs.
