When building today's (2005-01-14) gcc-trunk for different (cross-) targets on
FC3, I am seeing many (several 10ths) warnings of this kind:
...

In my understanding, this is the native gcc (gcc (GCC) 3.4.2 20041017 (Red Hat
3.4.2-6.fc3)) complaining about GCC-4.0.0 using "%q" as a format string.
I haven't tried, but IMO this probably results into GCC/c++ using non-functional
format strings.
