Symbolics (or is it ILA?) C environment

[connolly%livy@cs.umass.edu]

I'm curious as to people's opinions about the C environment that's
been built for the Symbolics (I don't remember whose product this
really is).

How is the function calling interface?  It is easy to call Lisp
functions from C, and vice-versa?  What kind of a C library exists,
i.e., does the C library reflect that on some popular version of Unix?
Is there a plan afoot to implement some dialect of C++?

Thanks in advance...
