I think a configure test based on -Werror=format would be sufficient
What we have now should work for GCC 2.0 and later, whereas -Werror=format is a much-newer GCC feature and so would be less portable.
if they are using some other compiler, then chances are -Wformat does not work, therefore the problem cannot be portably observed so there is nothing to work around
I am worried that other compilers might warn about it even without -Werror=format. (I'm not worried about GCC, as nobody uses GCC 1 any more.)
