If I understood the first two comments well, Akim doesn't want 
language-dependent code to pollute the Bison parser.  And I tend to agree.

The comments in Akim's last message are addressed by this revision of 
the patch.  The %skeleton mechanism is not touched at all.  People 
contributing new kinds of parsers will have to patch "c-lang.m4" and 
friends if they want the new skeleton to be selected automatically; it 
is not necessary however (and hence the patch is backwards compatible) 
if they prefer their users to use %skeleton in order to invoke the new 
feature.
