I take note.

They do no longer exist. cl_* refer only to lisp functions and not to
special forms so as to keep things consistent. You can, however, define
a simple macro
#define ecl_defparameter(s,v) \
do { si_Xmake_special(s); ECL_SETQ(s,v); } while (0);
I might include it in the next release. Seems harmless.
