It's a Forth variant that does typing, and lots of things that normal forth can't do... likely as powerful as Lisp, I think. It's become an obsession to get this thing running.
I do a wget, unzip, untar, ./configure, make, su make install and it works perfectly... under Debian 3
Anything newer, even with -std=c99, and it dies a horrible death.
Taking the executable from Debian 3 to Debian 11 (32 bit) and it works perfectly.
How do I, a non-C programmer, who is willing to dump tons of time into it, migrate this code into the year 2022?
Here's an example of something that seems opaque to me, from src/words.c:2012
*(--(char*)hash_ptr.parm.v.p) = fpop(sst);
