I've just sent to comp.sources.unix a new version of cdecl which adds
support for the new features of ANSI C and C++, as well as maintaining all
the old features of the old cdecl program. This includes all the new
keywords for the two new languages and function prototypes. The program
compiles on System V, 4.2BSD and MS-DOS; see the makefile for more
information on the different environments.
Here are the comments from the program which list all of the changes made.

NAME
cdecl, c++decl - Compose C and C++ type declarations
SYNOPSIS
cdecl [-a | -+ | -p | -r] [-cidDV] [files ...]
c++decl [-a | -+ | -p | -r] [-cidDV] [files ...]
DESCRIPTION
Cdecl (and c++decl ) is a program for encoding and decoding
C (C++) type-declarations. The C language (the default for
cdecl , or with the -a option) is based on the (draft
proposed) X3J11 ANSI Standard; optionally, the C language
may be based on the pre-ANSI definition defined by Kernighan
& Ritchie's The C Programming Language book (the -p option
is used), or the C language defined by the Ritchie PDP-11 C
compiler (the -r option is used). The C++ language (the
default for c++decl , or with the -+ option) is based on
Stroustrup's The C++ Programming Language, plus the version
2.0 additions to the language.
Cdecl reads the named files for statements in the language
described below. A transformation is made from that
language to C (C++) or pseudo-English. The results of this
transformation are written on standard output. If no files
are named, or a filename of ``-'' is encountered, standard
input will be read. If standard input is coming from a
terminal, (or the -i option is used), a prompt will be
written to the terminal before each line.
COMMAND LANGUAGE
There are six statements in the language. The declare
statement composes a C type-declaration from a verbose
description. The cast statement composes a C type-cast as
might appear in an expression. The explain statement
decodes a C type-declaration or cast, producing a verbose
description. The help (or ?) statement provides a help
message. The quit (or exit) statement (or the end of file)
exits the program. The set statement allows the command
line options to be set interactively.
Some synonyms are permitted during a declaration: character
-> char, constant -> const, enumeration -> enum, func ->
function, integer -> int, ptr -> pointer, ref -> reference,
ret -> returning, structure -> struct, and vector -> array.
