On windows, function name are 'mangled' by prefixing the name with an 
underscore or arobase and depending to the calling convention suffixed 
with the size of the arguments. Should this be done here?

http://en.wikipedia.org/wiki/Name_mangling#C_name_decoration_in_Microsoft_Windows

int _cdecl    f (int x) { return 0; }
int _stdcall  g (int y) { return 0; }
int _fastcall h (int z) { return 0; }

give:

_f
_g at 4
@h at 4

Cédric
