Hi Robert,

gm2 -g -c -fscaffold-main -fgen-module-list=filename -fscaffold-static 
-fno-exceptions $1.mod

are the closest equivalent options.  It will generate the scaffold and
main (but without generating the source).  The list of modules and order
is in filename.  The filename could be used of course to generate a C
scaffold - as of yet the Python3 tool hasn't been written.  I could add
one if necessary (with the same functionality as gm2lgen in the previous
releases)

hope this helps,

regards,
Gaius
