Oops. This problem will be solved automaticly when we read human readable 
configuration files. Still it will remain compatible. AFAIK configuration 
options can be overruled, this is a nice way to handle this IMHO.

Yes. I just wonder if a table already exists to map symbol names to numeric 
values. I think a C header (.h) file is used for this and that the Compose file 
is processed by the C pre-processor. I'm  going to search the code reponsible 
for deadkeys this evening :).
