Move definition on Parameters earlier in global.h

We typedef int * to Parmeters in global.h, but not at the same time as
the other typedefs.  This causes problems when we add a function
declaration for write_scrap().

This also highlights a random `1` being passed as the parameter in one
call to write_scrap().  This is obviously wrong, but the purpose of this
fix is to remove warnings - not do a deep dive into what the code is
doing.
