Thanks for the hint. However to me this looks like a workaround (or
even a hack) but not like a true solution.

From my perspective it seems reasonable to presume that the linker
together with the C/runtime library does "somehow make sure" that
main() is referred.

I understand that the linker fore sure isn't limited to C programs so
it doesn't make sense to hard-code such a reference but what about
i.e. extending the linker config syntax/functionality to allow
something analog to .forceimport (being kind of the "opposite" of
SYMBOL {}, maybe called IMPORT {}). The builtin linker configs could
then use that functionality for the symbol _main.

Best, Oliver
