Bug description

Hello,

the following

type t = t

neither compiles with nor without "-rectypes", whereas this

type t = u
and u = t

compiles with "-rectypes" (ocaml-3.02+5).

Shouldn't the two be treated the same way? (Not really important to me
unless this implies any real bugs, but anyway, you know my pedantry ;)

Regards,
Markus Mottl

Indeed, some recursion check was missing.
Thanks for reporting it.
