It looks like the way we build the engine via an assembler file and replaci=
ng=20
gforth_engine2 with gforth_engine fails on MacOS due to the _ prefix on the=
=20
symbol (sys_symbol_underscore=3Dyes on MacOS).

Edit engine/Makefile, search for ENGINE1, and add the necessary underscore=
=20
here:

ENGINE1 =3D -DSKIP4=3D -D_gforth_engine2=3D_gforth_engine

=2D-=20
