Browse Source 
* gdbarch.sh: Add FP0_REGNUM to list of multi-arched register numbers.
        * gdbarch.c, gdbarch.h: Regenerate.
        * core-regset.c: Change FP0_REGNUM to a runtime test.
        * procfs.c: Ditto.
        * sun3-nat.c: Ditto.
        * sparc-tdep.c: Ditto.

        * i386mach-nat.c: Remove unnecessary ifdef for FP0_REGNUM.
        * ptx4-nat.c: Ditto.

        * sol-thread.c (sol_thread_create_inferior): only add the thread
        to the thread list if it is not already in there.
        (prototypes for thread_db func ptrs): pretty up formatting.
