2000-05-08 Michael Snyder <msnyder@seadog.cygnus.com>
* 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.
