devel/cdecl: update to 11.9

ChangeLog:
Fixed reading from stdin
Fixed reading from stdin when it's not a TTY.

Redefinition check
Names being redefined with a different type in the same declaration are now correctly forbidden:

int i, i;                           // OK (tentative definition)
int j, *j;                          // error: different type
Function-like parameter redefinition check
Function-like parameters are now checked for redefinition (more than one parameter having the same name).

More C++ standard types
Added the standard C++ types std::ispanstream, std::stacktrace_entry, and std::wispanstream.
