[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 tangotests.mem2;

void main()
{
    int* ip = new int;
    assert(*ip == 0);
    *ip = 4;
    assert(*ip == 4);
    delete ip;
    assert(ip is null);
}
