Yes, this is the date of the last incompatible change to the bytecode.

I would not recommend to do this.

Indeed, you cannot use this .FAS file with newer CLISP versions.
- you get a not-so-new CLISP (available in the 199x-yy-zz/ directories
of the source/ and binaries/*/ directories on
- someone writes a "decompiler" that turns the bytecode contained in the
.fas file into some primitive Lisp code which can then be compiled
by a newer CLISP version.
