Do you still produce ALEX?  I had a problem with AFLEX in that it
had to get its input from text_io.  This brings up a question . . .

Why don't tools like AFLEX generate Ada generics?  That way, the 
user can provide the I/O functions:

with xx.token_type;
generic
   with function get_character return character;
   with procedure unget_character(char : in character);
   . . .
function yylex return xx.token_type;

I have modified aflex to use POSIX IO for input and allow the user to 
more easily provide the IO functions.  I havent cleaned it up enough
to send to arcadia, but it does work.  if someone wants it, send mail
to alex@cs.umd.edu.
