[Caml-list] Test case syntax error

Hello,

   I have added some functionality to the OCaml
run-time library and I am trying to test. I wrote test
case below that refuses to complile.

1) It gets a syntax error on the ending "done" for the
"while true". I have tried trimming down and still the
syntax error. I am sorry for something so elementary.
Can anyone help?

2) I am running on Linux. I did a "man ocamlc" to see
what kind of compiler switches there are. Is there a
compiler switch that gives a more verbose/helpful
error than simply "syntax error"?

Regards, vasili
