In my experience these convenience %? that we have got easily trigger 
warnings during bootstrap/build, eg:

/scratch/Gcc/svn-dirs/trunk/gcc/cp/error.c:3302:53: warning: unknown 
conversion type character ‘R’ in format [-Wformat]
/scratch/Gcc/svn-dirs/trunk/gcc/cp/error.c:3302:53: warning: too many 
arguments for format [-Wformat-extra-args]

I suppose we could do something about that...
