Bug description

ocamlc forms some ordinal numbers incorrectly in error messages.

The attached program causes an error message:

   Their 21th fields have different names, X and C.

"21th" should be "21st".

This replacement nth seems to do the right thing.

let nth n =
if n = 1 then "first" else
let n_100 = n mod 100 and n_10 = n mod 10 in
if n_10 = 1 && n_100 <> 11 then (string_of_int n) ^ "st" else
if n_10 = 2 && n_100 <> 12 then (string_of_int n) ^ "nd" else
if n_10 = 3 && n_100 <> 13 then (string_of_int n) ^ "rd" else
string_of_int n ^ "th"

Just reading the PR title, I first thought it was an April joke, and
found it funny. "?^? not printed correctly".

I'd suggest avoiding adding code for this issue and change the message instead. "Fields number 21 have..."

For the record, I am very much in favor of Xavier's solution. Our core business is not natural language processing.
