Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

In the TYPENAME case, DECLARATOR is really an absolute declarator.
It may also be so in the PARM case, for a prototype where the
argument type is specified but not the name.
This function is where the complicated C meanings of `static'
and `extern' are interpreted.
For C++, if there is any monkey business to do, the function which
calls this one must do it, i.e., prepending instance variables,
renaming overloaded function names, etc.
Note that for this C++, it is an error to define a method within a class
which does not belong to that class.
Except in the case where SCOPE_REFs are implicitly known (such as
methods within a class being redundantly qualified),
declarations which involve SCOPE_REFs are returned as SCOPE_REFs
(class_name::decl_name). The caller must also deal with this.
If a constructor or destructor is seen, and the context is FIELD,
then the type gains the attribute TREE_HAS_x. If such a declaration
is erroneous, NULL_TREE is returned.
QUALS is used only for FUNCDEF and MEMFUNCDEF cases. For a member
function, these are the qualifiers to give to the `this' pointer.
May return void_type_node if the declarator turned out to be a friend.
See grokfield for details. */

/* Decode the list of parameter types for a function type.
Given the list of things declared inside the parens,
return a list of types.
The list we receive can have three kinds of elements:
an IDENTIFIER_NODE for names given without types,
a TREE_LIST node for arguments given as typespecs or names with typespecs,
or void_type_node, to mark the end of an argument list
when additional arguments are not permitted (... was not used).
FUNCDEF_FLAG is nonzero for a function definition, 0 for
a mere declaration. A nonempty identifier-list gets an error message
when FUNCDEF_FLAG is zero.
If FUNCDEF_FLAG is 1, then parameter types must be complete.
If FUNCDEF_FLAG is -1, then parameter types may be incomplete.
If all elements of the input list contain types,
we return a list of the types.
If all elements contain no type (except perhaps a void_type_node
at the end), we return a null list.
If some have types and some do not, it is an error, and we
return a null list.
Also set last_function_parms to either
a list of names (IDENTIFIER_NODEs) or a chain of PARM_DECLs.
A list of names is converted to a chain of PARM_DECLs
by store_parm_decls so that ultimately it is always a chain of decls.
Note that in C++, parameters can take default values. These default
values are in the TREE_PURPOSE field of the TREE_LIST. It is
an error to specify default values which are followed by parameters
that have no default values, or an ELLIPSES. For simplicities sake,
only parameters which are specified with their types can take on
default values. */

/* [class.copy]
A declaration of a constructor for a class X is ill-formed if its
first parameter is of type (optionally cv-qualified) X and either
there are no other parameters or else all other parameters have
default arguments.
We *don't* complain about member template instantiations that
have this form, though; they can occur as we try to decide what
constructor to use during overload resolution. Since overload
resolution will never prefer such a constructor to the
non-template copy constructor (which is either explicitly or
implicitly defined), there's no need to worry about their
existence. Theoretically, they should never even be
instantiated, but that's hard to forestall. */

/* Create the FUNCTION_DECL for a function definition.

If PRE_PARSED_P is non-zero then DECLARATOR is really the DECL for
the function we are about to process; DECLSPECS are ignored. For
example, we set PRE_PARSED_P when processing the definition of
inline function that was defined in-class; the definition is
actually processed when the class is complete. In this case,
PRE_PARSED_P is 2. We also set PRE_PARSED_P when instanting the
body of a template function, and when constructing thunk functions
and such; in these cases PRE_PARSED_P is 1.

This function creates a binding context for the function body
as well as setting up the FUNCTION_DECL in current_function_decl.
Returns 1 on success. If the DECLARATOR is not suitable for a function
(it defines a datum instead), we return 0, which tells
yyparse to report a parse error.
For C++, we must first check whether that datum makes any sense.
For example, "class A local_a(1,2);" means that variable local_a
is an aggregate of type A, which should have a constructor
applied to it with the argument list [1, 2].
@@ There is currently no way to retrieve the storage
