These two lines

    static cl_object safe_eval = 0;
    if (safe_eval == 0)

used Cnil in Jim's original code.  I changed them[1] to use 0 because
using Cnil caused a compile error under Cygwin, I think because Cnil
is an offset to an array stored (in Windows) in a DLL, and thus the
compiler cannot calculate its address statically, and thus you cannot
assign it to a "static" pointer.  Jim didn't object.[2]

Any particular reason you changed them back?
