[Gabriel Bouvigne]

I've found a few info about various stack alignments there: 
http://www.agner.org/optimize/calling_conventions.pdf (see section 5)

Summary:

* x64 => mod16
* x86, gcc 3.x and upper, Linux and MacOS => mod16
* x86, gcc 2.x, Linux and MacOS => mod4
* x86, gcc 3.x and upper, Win32 => mod4?
* x86, ICL => mod4
* x86, Msvc, Win32 => mod4
