Summary: SDCC and structures

Initial Comment:
In the discussion forum on 2000-11-16 05:19, Carl van Schaik mentioned that
"It seens SDCC can't support arrays inside of structures..."

I've downloaded SDCC 2.3.0 and the problem that Carl mentioned still exists.

Here is an example:

struct structure
{
  short array[8];
} s;

void function( void )
{
  short  i;
  short *p;

  for( i=0; i<8; i++ ) s.array[i] = 0;
  //test.c(11):warning *** indirections to different types assignment
  //type --> 'char ' assigned to type --> 'unknown type '

  *(s.array + i) = 0;
  //test.c(15):error   *** Pointer required

  i += s.array[5];
  //test.c(18):error   *** invalid operand '+'

  p = s.array;
  for( i=0; i<8; i++ ) p[i] = 0;
  //workaround?
}

These errors only come up when "array" is short or long.  I don't get any errors when "array" is 
char.  This code compiles on other C compilers.
