[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 aa2;

void main()
{
    long[float] aa;
    long* p = 2.0f in aa;
    assert(!p);
    aa[4f] = 23;
    p = 4f in aa;
    assert(p);
    assert(*p == 23);
}
