I started thinking about this and I'm not sure how you can check for this at 
configure-time or build-time. While it would be easy to check what gcc version 
is being used, it is not so easy (dare I say, not possible) to see if 
gsm-formatted sounds are going to be used in this setup. Besides the fact that 
core sounds are not placed on the system until make install is run, we can't 
know if there are out-of-tree gsm-formatted sound files which will be used, too. 
Did you have something clever in mind for such a check?
