This strongly remembers me to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30510
Is it possible that some flags trigger the "warnings being treated as errors"
but most developers don't use this? That would explain why people stumble over
it while it seems to work after changes for the developers?!

I configured with:
/usr/local/src/gcc/configure
--prefix=/home/Marco/Desktop/compile-lin-lin/gcc-XYZXYZ-lin
--with-sysroot=/home/Marco/Desktop/compile-lin-lin/gcc-XYZXYZ-lin/sys-root
