I believe it used to be a signed type in Linux. Anyway, you can't
really change it, since on other OS'es the type defenitely is signed.
You'll only really notice this when the msb is set anyway. I think
this happens on the Linux threads implementation of today the thread
id isn't an integer at all, but a pointer instead. This suggests that
it should really be printed as an (unsigned) hexadecimal number.
Doing so doesn't need any changes to defs.h and therefore wouldn't
affect any other platforms at all.
