How to reproduce:
1. Install Debian on Windows Subsystem for Linux. Resulting system is "bullseye" release. 2. Download and unpack http://www.complang.tuwien.ac.at/forth/gforth/Snapshots/current/gforth.tar.xz. 3. Follow build from source instructions in "INSTALL.md". 4. "cd" into "vmgen-ex" or "vmgen-ex2". Both fail with the same error. 5. Type "make". Result is $ make bison -y mini.y && mv y.tab.c mini.tab.c mini.y:76.16-20: warning: POSIX yacc reserves %type to nonterminals [-Wyacc] 76 | %type <string> IDENT; | ^~~~~ mini.y:77.13-15: warning: POSIX yacc reserves %type to nonterminals [-Wyacc] 77 | %type <num> NUM; | ^~~ m4 mini-inst.vmg >mini.vmg vmgen mini.vmg in file included from *the terminal*:0:-94105607416479: in file included from *the terminal*:-1:1: /usr/local/share/gforth/0.7.9_20220428/prims2x0.6.2.fs:64:12: error: Undefined word : latestxt >>>lastcfa<<< @ ; Backtrace: /usr/local/share/gforth/0.7.9_20220428/kernel/int.fs:321:10: 0 $7F2477A41430 throw make: *** [Makefile:42: mini-gen.i] Error 243 This *does* work with "gforth" / "vmgen" from the Debian distro repositories.
