[Ecls-list] undefined-function function args

[Ilya Kliot]

Hi,
I want to add possibility to get the function args in the
(undefined-function) condition handler.
Is it possible to do without c source code changes ? Is there some
stack environment accessible by ready CL functions ?
Any hints how to make that ? I've tried to find it within
cl_env_struct but got lost, probably there are some ready functions to
get to invalid call in string form or something ? I will glad to merge
it after it will be done
