And actually, that whole cdecl thing only to satisfy windows is
overzealous, i.e. you only need to satisfy MSVC / x86, i.e. can
be simplified to an  #if defined(_MSC_VER) && defined(_M_IX86)
and even that shouldn't have been necessary because the windows
msvc (and mingw which follows msvc) default calling convention
is cdecl already.
