NAME
	MakeFunctions -- construct a function jump table

   SYNOPSIS
	tableSize = MakeFunctions(target, functionArray, funcDispBase)
	D0			  A0	  A1		 A2

	ULONG MakeFunctions(APTR,APTR,APTR);

   FUNCTION
	A low level function used by MakeLibrary to build jump tables of
	the type used by libraries, devices and resources.  It allows the
	table to be built anywhere in memory, and can be used both for
	initialization and replacement. This function also supports function
	pointer compression by expanding relative displacements into absolute
	pointers.

	The processor instruction cache is cleared after the table building.

   INPUT
	destination - the target address for the high memory end of the
		function jump table.  Typically this will be the library
		base pointer.

	functionArray - pointer to an array of function pointers or
		function displacements.  If funcDispBase is zero, the array
		is assumed to contain absolute pointers to functions. If
		funcDispBase is not zero, then the array is assumed to
		contain word displacements to functions.  In both cases,
		the array is terminated by a -1 (of the same size as the
		actual entry.

	funcDispBase - pointer to the base about which all function
		displacements are relative.  If zero, then the function
		array contains absolute pointers.

   RESULT
	tableSize - size of the new table in bytes (for LIB_NEGSIZE).
