Summary: Unecessary code generated in function calls.

Initial Comment:
The code for getting the function parameters

push ix
ld ix, #0
add ix, sp
[function boy]
pop ix

is generated even for functions without parameters, for
example

int test(void)
{
  return(2);
}

compiles into

push ix
ld ix, #0
add ix, sp
ld hl, #0x0002
pop ix
ret

where 4 out of 6 instructions do nothing.
