@sjoelund and authors: Updated patch includes proposed fix from #24 to use stdint.h. It also fixes the arguments of NOISE_shuffleDouble.

Compilation was tested with MSVC6, VS2010, BCC55 on Win and GCC 4 on Linux.

[sjoelund]

Pretty good, though I would prefer a typedef rather than a define (or using uint32_t directly, unless stdint.h was not available).

[tbeu]

Sure, but typedef fails on BCC55 why I changed it back to macro.

[tbeu]

@sjoelund OK, fixed in updated patch.

[sjoelund]

I closed #23 in favour of this patch

Thanks a lot! The patch works here, too. I will go ahead and merge it!
