[XeTeX] amssymb/amsfonts: Command `\Finv' already defined

[SONG Zhiwei]

  1 \documentclass{article}
  2 \usepackage{fontspec}
  3 \usepackage{xunicode}
  4 \usepackage{amsmath}
  5 \usepackage{amssymb}
  6
  7 \begin{document}
  8 $\mathbb{A}$
  9 \end{document}

Maybe xunicode and amssymb are fighting.
