Linux and Windows returns 0, I don't have access to other platforms.

I actually read the DJGPP keyboard code of Allegro in ored to understand what 
is going on when a key is pressed, but I got lost. Maybe I looked into the 
wrong files. 
I thought that misc/pckeys.c:_handle_pckey() was a candidate. A key shift 
table is used, which seems to contain 0xffff, for the concerned codes. When 
coming to _handle_key_press I think data should be platform independent.
