With gcc-1.40, on a SS1(SunOs 4.1), the following program outputs 0 :

#include <varargs.h>
unsigned short int i=80;
int f(
      va_alist
)
{
  va_list ap;
  unsigned short int j;
  va_start(ap);
  j=va_arg(ap, unsigned short int);
  va_end(ap);
  return((int)j);
}

main(
)
{
  printf("%d\n",f(i));
}

With /bin/cc, it outputs 80.

Is it a bug of gcc ?
