What are you doing here? These should already be included by the
template. You should not have to do anything else.

You should not be changing this. There is no implementation header,
the POSIX implementation uses the default definitions in the isoinfra
package. This is most probably the cause of your problems.

Try build without changing any of the config options. Just
configure with the POSIX template and build. Once that works (as it
should), then you can go in and change things like the maximum number
of queues. Resist the temptation to fiddle with anything else.
