Update to FICL 3.03 (the last release before FICL4 rewrite). The relevant changes for FreeBSD (excerpt from the release note): * Newly implemented CORE EXT words: CASE, OF, ENDOF, and ENDCASE. Also added FALLTHROUGH, which works like ENDOF but jumps to the instruction just after the next OF. * Bugfix: John-Hopkins locals syntax now accepts | and -- in the comment (between the first -- and the }.) * Bugfix: Changed vmGetWord0() to make Purify happier. The resulting code is no slower, no larger, and slightly more robust.
