Summary: Extern declaration of multi-dimensional arrays and structure

Initial Comment:
Hi guys,
Problem in sdcc 2.4.7: Extern declaration of
multi-dimensional arrays and structures:

unsigned char key[4][MEM_KEY]
extern unsigned char key[][]; // does not work
extern unsigned char key[4][MEM_KEY]; //works

struct eventData {unsigned char event; unsigned char
target;};
struct eventData keyTimer[NUM_KEYTIMER];
extern struct eventData keyTimer[NUM_KEYTIMER]; // does
not work

Compiler produces no error message, but code doesn't
work. Used no special command line parameters. Cannot
send you more code, because it is very
hardware-specific. The structure example worked in sdcc
2.4.0.

Sorry, I cannot see where it goes wrong in the assembly. I
attach  a file, once compiled with version 2.4.0 and the
same file compiled with 2.4.7. if that helps.
I guess that it has to do with struct eventData
keyTimer[NUM_KEYTIMER]; if I reduce the array size to 1 it
works.

The code you presented cannot "work" as there are no 
instructions, only declarations. Please be a little more 
elaborant on what doesn't work. Can you see where it goes 
wrong in the assembly? If you can create a little example 
source and upload it here that would be even better.
