Problems with ABNT2 Layout

Dear sirs,

    There's a missing key on the ABNT2 Layout. The Brasilian Keyboard 
uses 49 keys instead of only 48 for the others. It uses the key named 
VT_OEM_5 as backslash key ("\|"). The keyboard.c has the correct 
definitions for lowercase and uppercase for the first 48 keys, but i 
couldn't find a way to map the last one. It also lacks the <ALT GR> 
keycodes.

    I'm sending bellow the complete keycodes. I also included the 49 
keycode, but it requires some changes inside the keyboard.c to operate 
with the last one, as stated on the following lines.

    I would also to ask how to use dead keys for generating accents. On 
Brasilian Portuguese keyboards, when you press *'a*, for example, it 
will convert to *á*  (a acute).

#define MAIN_LEN *49*
static const WORD main_key_scan_qwerty[MAIN_LEN] =
{
/* this is my (102-key) keyboard layout, sorry if it doesn't quite match 
yours */
