The change makes sense, but I would remove the other two declarations
as well, as extern declarations don't belong into .c files.

As far as I can tell, modehscx() already has a declaration in hscx.h,
while hscx_l2l1() doesn't, and the declaration here should be
moved as well.

For consistency, I would add 'extern' here. We normally leave that out,
but I think if there are lots of declarations in a header file that all
have it, it's better if they are all the same.
