Thread-safe questions in configure

I have two questions about the support for thread-safe clients in
configure:

configure sets NEED_REENTRANT_FUNC_NAMES=no, overwriting the template
setting. Why?

Forgot to remove it when I moved the stuff to templates.

The check for reentrant functions says:

# Include special flags if threads are enabled _and_ if required for
# threading on this platform. Some platforms have *_r functions but
# their natively named funcs are threadsafe, and should be used instead.

But the actual check does not check if "threads are enabled", only if it's
required on the platform (which doesn't work -- see above).

Is this some kind of transition state "to be fixed later"?

The only transition state is in my head. :-)

Patch attached and applied.
