remote.c:	when compiled with 32-bit int, the define INT_MAX is 2^32-1 and

		the remote array defined in the test is too large for the hc11

		(48K).  The prog compiles but does not link due to this large array.


call-ar-st.c: 
the resulting program is too large when compiled with 32-bit int.
		It compiles but the link fails.

callfuncs.c: 
this one is probably a limitation of gdb.  When a char is passed
		as parameter, it is passed as a 16-bit value (for HC11/HC12 gcc port).
		Gdb assumes that it is passed as an int, which is 32-bit without gcc -mshort
		option.
