A somewhat outdated release. You may want to upgrade to 2.95.2 or higher.

Note that this is _not_ an error message. It's just a warning, and you
get it because unlike the docs, or our library *GCC* itself does not
know about 'U' format in *printf() functions. That's not a surprise,
either --- it's a nonstandard format. Use the standardized format
specifier "%lu" instead, and both you and GCC will be happy with it.
