Bug in pthread_equal

There seems to be a bug in pthread_equal:
int pthread_equal(pthread_t t1, pthread_t t2)
should return a non-zero value if t1 and t2 refer to the same thread, and a
zero value otherwise. With the Cygwin DLL 1.3.2 implementation, it is the other
way around: the function returns zero if t1 and t2 refer to the same thread,
and a non-zero value otherwise.
One way to solve this would be to change
cygwin-1.3.2-1/winsup/cygwin/thread.cc, at line 1811: replace
int
__pthread_equal (pthread_t * t1, pthread_t * t2)
{
return (*t1 - *t2);
}
with
int
__pthread_equal (pthread_t * t1, pthread_t * t2)
{
return (*t1 == *t2);
}
(I did not test this, though.)
