Solaris-i386 ABI is also supposed to conform to abi386-4.pdf.
In section 3-10 it says: "The stack is word aligned. Although the 
architecture does not require any alignment of the stack, software 
convention and the operating system requires that the stack be aligned 
on a word boundary."
But I know for the fact that Solaris-i386 uses 16 byte alignment. At 
least that's what gcc-4.5.2 thinks when on Solaris.

Still not sure about FreeBSD-i386.
