[svn r327] Fixed some more MinGW32 issues. It's now very close to working. Fixed problems with inline asm like: mov EAX, FS:4 , which incidentally is used in the runtime to get the stack bottom, on Windows.

module classinfo2;

class C
{
}

class D : C
{
}

void main()
{
    D d;
    d = new D;
    ClassInfo ci = d.classinfo;
    assert(ci is D.classinfo);
}
