the compiler doesn't warn about bits being lost -- it complained
because the code was returning a pointer from a function declared
to return a long integer.
(explicitly casting the pthread_t to a long gets rid of the warning).

probably. messing up when someone abuses pointer casts is one thing,
but if the AIX compiler cannot cast a long to a long, it's broken beyond
repair ;-)
frankly, the code is just plain broken. instead of adding even more dumb
hacks, just fix it. here's how it should be done:
return (long) pthread_self(); /* look! no variables! */
or change
/* Jump through some hoops for Alpha OSF/1 */
to
/* Jump through some hoops because Tim Peters wants us to ;-) */
