given this code:  
  
=== Cut ===  
static const char * const tcvnlocales[] = { "vi", 0 };  
=== Cut ===  
  
There should be a "defined but not used" warning.

Never mind, but I can tell you this was already fixed by the time 4.0.0 was branched.
Try with -Wunused.

IIRC, this was intentional because people had a habit of writing RCS 
"$ID:" strings at the top of files and wanted to find them again in 
the executable to identify which files exactly were linked together. 
 
You may find relevant discussions somewhere in the archives.

this is where __attribute__((unused)) kicks in..
