constructors and multiple entry points

[Gabriel Dos Reis]

Hi,

   We're assessing many proposals to add "forwarding constructors" and
forwarding functions to C++0x; and I got a question.

   In standard C++, constructors cannot be recursive functions.  I'm
wondering whether the multiple entry-points implementation strategy used
by GCC depends in anyway on the absence of recursive definition.

Thanks,
