--- Comment #3 from Eddie Nolan <eddiejnolan at gmail dot com> ---
Fixed (first two commands were superfluous):

echo "module1 module1.gcm" >> ./module1.cpp.o.modmap
echo "module2 module2.gcm" >> ./module2.cpp.o.modmap
echo "module1 module1.gcm" >> ./module2.cpp.o.modmap
g++ -I./include -g -std=c++20 -MD -MT ./module1.cpp.o -MF ./module1.cpp.o.d \
    -fmodules-ts -fmodule-mapper=./module1.cpp.o.modmap -MD \
    -fdeps-format=p1689r5 -x c++ -o ./module1.cpp.o -c ./module1.cpp
g++ -g -std=c++20 -MD -MT ./module2.cpp.o -MF ./module2.cpp.o.d \
