Allegro.log attached. Here's what the top row of my keyboard looks like, if 
that helps:

  1   2     3     4     5     6     7     8     9     0
  &   é ~   " #   ' {   ( [   - |   è `   _ \   ç ^   à @

As expected, the 4th and 6th keys get assigned KEY_QUOTE and KEY_MINUS, and 
the others get random constants. I'm not sure there is much you can do about 
that. KEY_0 and co. are just part of the constants that only make sense on a 
QWERTY keyboard.

Sorry, I expressed myself poorly. Dead keys work exactly as you describe, but  
as a side effect, they set key[0]. Not really a problem, but I thought you 
might want to know.

That'd be wonderfull, thanks!

I can help if you need. Also, can't you use OpenGL unaccelerated ? That might 
be enough to test. Or maybe this is a problem for Bob to fix ;-) Should I 
report on [AGL] ?

Anyway, here's what I could gather after a bit of investigation :

The AllegroGL examples that fail are dumbtest, exgui and exalleg. They have in 
common that they use rect() and rectfill() directly, or indirectly through 
gui objects. After commenting these use, they work fine. Does that help ?

Also, in my program the problem was a locale problem: it seems the new 
install_keyboard somehow changes part or all of the program's locale to that 
of the keyboard layout. This is a problem with Lua, because it is known not 
to work in a locale where the decimal point is not a dot. If I put a 
setlocale(LC_ALL, "C") after install_keyboard, my program works again. Yay! 
(I don't use any allegro functions like rect).
