72e2ca0e8e Give all functions a formal prototype. 
This makes the code C89 compliant, and removes all warnings on macOS.

124b7550ab 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.

cbcfc68afa Correct prototype of write_tex(). 
In a reverse of write_html(), write_tex() is declared with three
parameters, but only called with two.

Removing the third parameter is fine as it is unused.

a44adf4baf Correct calls to write_html() 
write_html() is declared as taking two parameters, but the call to it
passes three.

We fix this by dropping the third parameter, which was labelled 'DUMMY'
anyway.
