Reproduced for 088d089 commit on Linux 64, fcc build with GCC 11.1.

GNU readline is GPL licensed, so things containing it need to be open source themselves. I'm not a lawyer, but I think the Apache-licensed FCC is okay for now. But shipping a closed-source binary built using FCC that linked against GNU readline would not be okay.

editline and its dependency ncurses have less strong licenses (BSDish and X11/MIT respectively) which are compatible with shipping a closed-source binary that links against them.

Modeled on Gforth's system, probably. Ideally compatible. Looks like running the compile commands in the background and then using dlopen() support will work.

That's not portable to non-POSIX platforms, but there are equivalents on Windows.

If the target word is not found, these parsing words silently fail. They should produce the same error message as trying to interpret/compile such a missing word.

Like a search tree or something, I don't know what's best.

Probably do multiple wordlists at the same time, add that extension word list.

Currently missing:

• .R, HOLDS, and U.R
• 2>R, 2R> and 2R@
• C" and S\"
• CASE, ENDCASE, OF, ENDOF
• MARKER
• RESTORE-INPUT and SAVE-INPUT
• [COMPILE] (obsolete, maybe skip?)

Better for portability than linking them from the filesystem. More annoying for development, though.
