hi all!

GENERIC compile failed. I try to compile by NetBSD-current 20050118.

The cause is as follows. 

  In file included from ../../../../arch/mips/mips/mips_machdep.c:153:
  mips/frame.h:51: field `sf_sc' has incomplete type

variable `sf_sc` is type `struct  sigcontext`. However, Its defined by
mips/signal.h. And, COMPAT_16 is not defined in GENERIC.  

mips/signal.h ---

#if defined(_LIBC) || (defined(_KERNEL) && (defined(COMPAT_16)))
struct sigcontext {
        int     sc_onstack;     /* sigstack state to restore */
        int     __sc_mask13;    /* signal mask to restore (old style) */
        mips_reg_t sc_pc;       /* pc at time of signal */
        mips_reg_t sc_regs[32]; /* processor regs 0 to 31 */
        mips_reg_t mullo, mulhi;/* mullo and mulhi registers... */
        int     sc_fpused;      /* fp has been used */
        int     sc_fpregs[33];  /* fp regs 0 to 31 and csr */
        int     sc_fpc_eir;     /* floating point exception instruction reg */
        int     sc_xxx[8];      /* XXX reserved */
        sigset_t sc_mask;       /* signal mask to restore (new style) */
#endif /* _LIBC || _KERNEL */

--- mips/signal.h

Please define COMPAT_16 in GENERIC.
I defined COMPAT_16 (and COMPAT_20). I was able to build it.  :)
