When compiling aalib 1.0.5 on x86_64 with gcc 4.3.2 and --enable-Werror,
compilation fails with messages like these:
cc1: warnings being treated as errors
malloc.c: In function '__chunk_free':
malloc.c:164: error: cast from pointer to integer of different size
An updated patch based on a patch from Mandriva is attached here. Could
you review the patch for its correctness and apply it if it's correct?
Thanks,
