=========================

The function is:

void s32tos16x(int32 *lp, uint32 c)
{
  int16 *sp=(int16 *)(lp);
  int32 l;
  while (c--)
    {
      l=(*lp++)>>(32-16-GUARD_BITS);
      if (l > 32767) { l=32767; output_clips++; }
      else if (l<-32768) { l=-32768; output_clips++; }
      *sp++ = XCHG_SHORT((int16)(l));
    }
}

========================

From what I can tell, the problem is in machine/endian.h, where
__byte_to_word is defined as:

#define __byte_swap_word(x) \
__extension__ ({ register u_short __X = (x); \
   __asm ("xchgb %h1, %b1" \
        : "=q" (__X) \
        : "0" (__X)); \
   __X; })


=======================

Adding

#include <sys/types.h>

to the top of output.c appears to fix it, as its required to define
u_short in the above ...
