Add lint-style FALLTHROUGH annotations to fallthrough cases. (in the parse engine and thus the output code) Document this, because the old output causes warnings with gcc10.

# subdir.mk - recurse into subdirectories, in portable make.
#
# Before including, set:
#    SUBDIRS                     directories to recurse into
#    MORESUBDIRS                 extra directories for rules and distclean
#    TARGETS (optional)          all targets to provide
#    MORETARGETS (optional)      additional targets to provide
#    MYDISTCLEANFILES (optional) files to remove at distclean time
#
# Note that directories may be listed in both SUBDIRS and MORESUBDIRS
# without causing things to duplicate.
