Please reply to me in person, as I had to unsubscribe from djgpp due to email
intray overload: I will be away from my email over Xmas and New Year.

I have djgpp v2. A program contains a switch(c){  } statement which is obeyed
very many times. c can be from 0 to 511. How can I make djgpp compile the
switch() always as a lookup table of labels and not as a lot of time-wasting
tests and jumps even if the resulting lookup table would be very gappy? I
can't find anything about this in DJGPP\INFO\ or in the FAQ.
