Borland build fixes (from Yitzhak)

> This patch fixes warnings relating to pointers (using int *
> instead of unsigned int * ), provides prototypes for some
> functions, and adds a missing argument to one of the functions
>
> It also changes a bit in the way flex/bison are used in the
> Borland makefile to allow me to test compilation with those
> utilities using a batch file.
