Build log

Hello,

you're receiving this canned bug because the package in summary uses the flag -Werror during build, which transforms warnings in errors, and is prone to break software when new GCC releases are added to Gentoo.

Please make sure your package does not use -Werror during build, so that it can be more future-proof for the new GCC releases.

Thanks,
Diego

The first warning is completely bogus.  It is both unhelpful (it quotes code that doesn't exist in the source; the 'uninitialized' value is given in the wrong file) and false (the code looks pretty straightforward to me).  Fixing the code would just validate gcc, so I fixed all makefiles.
