It matters in the sense that Wine currently doesn't clear the direction
flag before calling an exception handler, so if MSVC doesn't do a cld
then we'd have the same bug WRT msvc as the Linux kernel has WRT gcc.
Of course now that gcc is changed we'll have to make sure to clear the
flag regardless of what MSVC does.
