You're probably using 2.5, the version most commonly packaged with Linux
distributions.  The cdecl.org site uses that same old version.

This entire thread is about the newer version available at
<https://github.com/paul-j-lucas/cdecl/>.  It doesn't have that bug.

$ cdecl --version
cdecl 18.6

$ cdecl explain 'void foo(char *const)'
declare foo as function (constant pointer to character) returning void
$ cdecl explain 'void foo(char *const foo)'
declare foo as function (foo as constant pointer to character) returning void
$ 

(I'm not entirely pleased that the newer version expands "char" to
"character" and, worse, "int" to "integer", but I can live with it.)
