New description:

 For those processors which have a builtin floating point unit there needs
 to be a way to specify whether or not posix threads (created with
 pthread_create) need to to save/restore the floating point context during
 a context switch.  This is already the case for RTEMS tasks.  I am
 submitting a patch for both rtems-4.10.2 and newlib-1.19.0 to accommodate
 a new field is_fp to the  pthread_attr_t structure declared in
 newlib-1.19.0/newlib/libc/include/sys/types.h, declarations for 2 new
 functions in newlib-1.19.0/newlib/libc/include/pthread.h.

 And the functions themselves to be added to rtems-4.10.2/cpukit/posix/src.
