[Python-Dev] pthreads question: typedef ??? pthread_t and hacky return statements

[Greg Stein]

That is a silly approach, Tim. This is exactly what autoconf is for. Using
run-time logic to figure out something that is compile-time is Badness.

And the "but it will eventually be fixed" rationale is bogus. Gee, should we
just start loading bogus patches into Python, knowing that everything will
be fixed in the next version? Whoops. We forgot some. Oh, we can't change
those now. Well, gee. Maybe Py3K will fix it.

I realize that you're only -0 on this, but it should be at least +0...

Cheers,
