This is not a general "migrating from gcc 4.1.x version to gcc 4.8.x problem". It compiled previously, maybe by chance or maybe because you had a different glibc, which is not part of gcc, and so nothing to do with migrating to a newer gcc. For whatever reason, now it doesn't compile, because there are two different declarations for getline. getline is a standard function, defined by POSIX, so it will be defined by <stdio.h> and any code that includes <stdio.h> cannot declare a different function called getline. So as I already said, remove the bad declaration. Rename it, or remove it, or whatever you need to.
