If your code relies on ULstrncmp(s1,s2,n) as provided in libutil.a and
defined in andrew/overhead/util/lib/ulstrcmp.c beware that as of the
next patch the value returned by that routine will be correct!  The
comment for that routine is correct but it now actually returns the
opposite magnitude.

int ULstrncmp(s1,s2,n)
char *s1, *s2;
int n;
{
  /* case INSENSITIVE:  Compare strings, up to n chars:  
     s1>s2: >0  s1==s2: 0  s1<s2: <0
   */

  register int i;
  register int result = 0;

  for(i = 0;(s1[i] || s2[i]) && i<n && !result;++i){
    result = DOWNCASE(s2[i]) - DOWNCASE(s1[i]);
  }
  return(result);
}


If you have any code that looks like;

  if( ULstrncmp(s1,s2,n) < 0 ) break;

it will have to be changed to be:

  if( ULstrncmp(s1,s2,n) > 0 ) break;
