thread.fork errors

On Windows 64 thread.fork doesn't load properly. In the Max console we get:

error 126 loading external thread.fork

@wagne342 thanks -- I was able to fix the loading issue by statically linking the pthread library, so the object loads now, but it seems like it's not doing anything when I send messages in, so it will require some more attention.

[ramagottfried]

so the original issue is fixed, but on more testing there seems to be some funkiness in 64bit on Mac as well. On my system when sending a max message into thread fork the result is garbled when coming out of thread.join -- whereas it works fine in 32bit mode.

on windows, in both bit modes, it loads now, but has no visible response when you send any input into thread.fork.

also, sometimes it crashes in 64bit mode:
