I've read the POSIX spec, and it looks like pthread.h should include
unistd.h so that the #defines you refer to are properly defined. 

Solaris 2.5.1 pthread.h doesn't include <unistd.h> directly, but does
include <sys/signal.h> which includes <unistd.h>.

I think our pthread.h should include <unistd.h>, but don't know if
it should be directly included or not.

Jason, what do you think?
