compilers that self compile

["Antonio S. de A. Terceiro" <asaterceiro@inf.ufrgs.br>]

Hello all,

How do people in Debian handle compilers that depend on itself to
be compiled?

More precisely:

   * can a package build-depend on itself? I've saw that gcc, for
     example, don't (at least explicitily) build-depend on itself.
   * how packages like those go in the repository for the first time?

I couldn't find references about that on either in Debian Policy Manual
or in Debian Developer's Reference. If I missed something, please point
me were.
   
Regards,
