Overlay error message upon Make

I get the error message " ‘_entry_scn’ type is non-overlay and absolute but occurs in more than one input file. " when I include the necessary header files in Kevin’s streamlined camera code 21 in user_routines_fast.c.
What does this mean and how can I remedy it?

If you search the forums for _entry_scn you will find a lot of useful discussion. This thread, for example.
