Recent changes to attribute handling in GCC fix some *really important*
problems with handling of attributes in C++, particulary with dllimport of
class definitions.

        PR c++/3395
        * decl.c (xref_tag): Remember early attributes in TYPE_ATTRIBUTES,
        not TREE_TYPE.
        * semantics.c (finish_class_definition): Adjust.

        Allow attributes in parms and casts.
        * parse.y (named_parm): Don't strip attrs.
        (declmods): Remove 'attributes' production.
        (nonempty_cv_qualifiers): Accept attributes.
        (ATTRIBUTE): Give precedence.
        * decl.c (groktypename): Handle attributes.
        (grokparms): Likewise.

However they also cause parse errors at four places in the w32api
headers (but only with C++);

rpcdce.h:362:DECLSPEC_NORETURN void  RPC_ENTRY
RpcRaiseException(RPC_STATUS);
winbase.h:1059:DECLSPEC_NORETURN void WINAPI ExitProcess(UINT);
winbase.h:1060:DECLSPEC_NORETURN void WINAPI ExitThread(DWORD);
winbase.h:1095:DECLSPEC_NORETURN void WINAPI
FreeLibraryAndExitThread(HMODULE,DWORD);

The parse errors can be fixed quite simply by putting the
__attribute__((noreturn)) at the end of the prototype rather than the
beginning in the w32api headers. 

I am not going to report this as a bug to GCC yet since the local fix is so
easy. Placing the attribute after the function is the logical (sensu GCC)
thing to do anyway. 

Just a heads up for others testing GCC.
