        * gregset.h: New file.  Typedefs for gdb_gregset_t and
        gdb_fpregset_t, prototypes for supply_gregset and friends.
        * procfs.c: Include gregset.h.  Delete local prototypes for
        supply_gregset etc., and local typedef gdb_gregset_t etc.
        * sol-thread.c: Include gregset.h, delete local prototypes,
        add appropriate casts to gdb_gregset_t.
        * uw-thread.c, lin-thread.c, core-sol2.c, core-regset.c,
        sparc-tdep.c, ptx4-nat.c, ppc-linux-nat.c, mipsv4-nat.c,
        m88k-nat.c, m68klinux-nat.c, m68k-tdep.c, irix5-nat.c,
        irix4-nat.c, ia64-linux-nat.c, i386v4-nat.c, cxux-nat.c,
        arm-linux-nat.c, alpha-nat.c: Include gregset.h.
        * config/nm-linux.h: Define GDB_GREGSET_T, GDB_FPREGET_T.
        * config/sparc/tm-sun4sol2.h: Ditto.
