Bad interaction between camlp4o and optional arguments #4937
Original bug ID: 4937
The following program is incorrectly preprocessed by camlp4 :
~ 12:59:36 $ cat rien.mli
Sorry I couldn't guess the source of the problem !

Yes the problem appears to be similar to issue 4884 (apologies for missing that one), but I should stress that in my case camlp4 is necessary for the problem to appear :
ocamlc -c rien.mli
works just fine. Anyway thanks for this lightning-fast reaction !
