A forward-declared (or not yet fully defined) type must be used
to construct (mutually) recursive type declarations. This simplifies
the compiler and resolves the issue at which scope the forward-
declared type is to be declared.

use string* to pass it around.

SVN=114795

declaration of a func does not exactly
match the actual (or another foreward)
declaration. the reason is that when
there are 2 declarations of a function,
the names of the parameters are taken
from the first. thus
   func x(a int);
followed by
   func x(b int) { ... }
will have the parameter named "a" and
"b" will be undefined.

SVN=114788

fixed error in symbol table in
the second forward declaration of
a function.

SVN=114572

without conversions
