As long as these diagnostics by default do not cause the compiler to 
exit with nonzero status, we should be OK with Autoconf-generated 
'configure' scripts. Although there will be problems with people who run 
"./configure CFLAGS='-Werror'", that sort of usage has always been 
problematic and unsupported by Autoconf, so we can simply continue to 
tell people "don't do that".
