Thanks Vaclav, you're absolutely right.  On further investigation, this
turned out to be due to the fact that the program is expecting 'pthread_t'
and 'pthread_key_t' to be equivalent.  When they were both unsigned long,
the compiler would perform a cast automatically.  However, when they're
both pointers to struct, the compiler (understandably) complains.  In this
case I should be able to get around the problem by casting, unless you
can think of a better solution?
