Is AdaCore maintaining GNU Binutils on AIX? I do not believe that Binutils implements some toolchain changes to AIX 6.1 and AIX 7.1. Using Binutils means someone keeping it up to date with AIX. On the other hand, if there is enough external interest in GNU Binutils, IBM may lose control of the toolchain for its platform. Thanks, David
