[Numpy-discussion] rational custom dtype example

I have noticed a few issues with the "rational" custom C dtype example.

1.        It doesn't build on Windows.  I managed to tweak it to build.  Mainly, the MSVC9 compiler is C89.

2.       A few tests don't pass on Windows, due to integer sizes.

3.       The copyswap and copyswapn routines don't do in-place swapping if src == NULL, as specified in the docs.
