I tried to contact the original authors, and indeed got quite far along and got permissions from several, but unfortunately a key original author could not be contacted. If you want I can go back over my notes and dig out the names again.
This is what Tony Hansen said to me back in January 2007 when I contacted him (it was a private email so I have removed parts):
Yes, I'm one of the early contributors to cdecl. These are the contributors I see mentioned in my copy of the source: Graham Ross, once tektronix!tekmdp!grahamr, now Context, Inc. * originally written David Wolverton, david_wolverton<@>att.com * conversion to ANSI C * added some bug fixes from D. Wolverton * add typedef support * remove noalias Merlyn LeRoy, merlyn<@>rose3.rosemount.com * added extern, register, static * added links to explain, cast, declare * separately developed ANSI C support Alexander Dupuy, dupuy<@>smarts.com, dupuy<@>cs.columbia.edu * modified type crosscheck to warn about void/signed in ritchie, * preansi * #undef yywrap so that flex can be used * better semantic checking on use of C++ references * support const/volatile function member pointers Unknown * modified to provide hints for unsupported types * added argument lists for functions * added 'explain cast' grammar * added #ifdef for 'create program' feature Myself * added function prototypes * added C++ declarations * made type combination checking table driven * added checks for void variable combinations * made 'create program' feature a runtime option * added file parsing as well as just stdin * added help message at beginning * added prompts when on a TTY or in interactive mode * added getopt() usage * added -a, -r, -p, -c, -d, -D, -V, -i and -+ options * delinted * added #defines for those without getopt or void * added 'set options' command * added 'quit/exit' command * added synonyms * merged versions from LeRoy * added tmpfile() support * allow more parts to be missing during explanations * added some bug fixes from D. Wolverton * add typedef support * remove noalias * fixed some memory leak problems pointed out * by the "purify" program * add support for ... * now a command line argument may have more text than just the * keyword
[and he goes on to say that he is happy to relicense his changes under a free license].
Graham Ross is the original author and the man whom we need to contact most of all. I'm pretty confident that with his go-ahead we could relicense the whole thing, since the other contributions are just minor derived works of the original.
The last place I found Graham working was thinkshare.com, however that email now bounces.
