# Note: on ARM we added ' -DBUILD_SHARED_LIBS=OFF ..' otherwise
# the linker doesn't pick up one of the functions in the 'msc' library.
# There are no shared objects shipped in the Slackware package, so - this works for me.
# I know that it's *enabled* further up in the list below, but I'm leaving that in place
# since it makes it easier to merge changes from Slackware upstream.
# Mar-2021: it's included in x86 build now.
