I downloaded this package, but the executable inside seems to be not a DJGPP
program, and there are no instructions how to build with DJGPP. So I
couldn't compile and try to run it.

The second program is indeed a DJGPP one, but it seems to be compiled with
DJGPP v2.01. There are no sources, so I couldn't recompile. Running the
executable on DOS 5.0 doesn't show any problem with keyboard locks.
So I couldn't reproduce the problems you were describing. Could you please
post instructions how to download the sources, how to compile the programs,
and how to run them (with what data files) in order to reproduce the
problems?
