* Makefile.am, configure.ac: Add test case for the
_Thread_queue_Enqueue_priority interrupt critical section where the
TCB we are using as a current pointer is removed from the thread
queue when we flash interrupts while searching forward.
* spintrcritical06/.cvsignore, spintrcritical06/Makefile.am,
spintrcritical06/init.c, spintrcritical06/spintrcritical06.doc,
spintrcritical06/spintrcritical06.scn: New files.
