Summary0005974: Seeds do not generate same worlds between different OSs
DescriptionReddit thread for where this was first noticed: http://www.reddit.com/r/dwarffortress/comments/u2ptk/this_is_the_most_fun_ive_had_in_dwarf_fortress/c4s1m21

If seeds are used to generate a world on one Operating System, say linux, then the same seeds will not produce the same world in different Operating systems, say Windows XP or Windows Vista.

I tested the seeds on my machine running linux and it generated the same world, I then tried the Seeds on a different computer running windows and the worlds were different. Also the results were different between my computer running windows XP and another redditors running windows Vista, both running 32 bit.

Other user reported generating the same world after rebooting into a linux installation on the same machine.
Steps To Reproduce1) Generate a world using WORLD_GEN parameters in Additional Information
2) Compare with http://dffd.wimbli.com/file.php?id=6382
