"...Both C and LISP are ANSI standard languages."

[masinter.pa@XEROX.COM]

While we're slugging away to create an ANSI Standard for Common Lisp, it is
a time-consuming process. We're hoping that there will be draft next year;
after a draft is published, there is a period of public review before it
becomes an ANSI standard. I believe the process for C is further along, but
then, C is a much simpler language; there is no ANSI standard C library,
for example.

There is also a separate group trying to create an ISO standard for ISLISP.
(Not for "Lisp", by the way.)

The "windows" subcommittee of X3J13 has been dormant -- apparently no one
was willing to invest any energy into sorting out the similarities and
differences among the competing systems.
