It should default to --with-threads=posix, which you'll need for the
threaded listener (it just means that the system supports posix
threads). You can either specify that explicitly or trust configure
to get it right (you can examine the output of configure to check that
it got it right -- but I'm sure it did).

parameters for us to offer a configure parameter for each one of them.

But you can set the global config file to set this MCA param value by
