# Unfortunately, CCE 18 and 19 incurred a bug in the lower-casing of
# submodule .smod files, leading to incomplete lower-casing of the output
# file name, e.g., `parent_mod.sUB_MOD.smod`.
# This is supposedly fixed in CCE20, but we have to switch off the use of
# lowr-casing, thus only using the `-em` option for versions in-between.
