No.  This isn't a portable feature.  I plan on adding a feature that's
similar, and portable, but that's why asked why you need this.  I'm not
sure the portable interface will suffice for your needs with out knowing
what they are.

Casting this way is non-portable.  And I don't believe POSIX requires
pthread_t to be a pointer, though I haven't researched that in depth yet.
