If it is the latter, then this is sort-of okay as a final solution, but it is the former, I'm stll frowning upon this solution.

I have tried creating own .so libraries and the symbol lookup has worked just like on linux. So, it seems like we need workarounds only for special AIX stuff.

My understanding is that a lot of symbols can be found out of the box because they are in dynamically linked libraries. Only some libraries are special on AIX which don't support dynamic linking and we need this workaround for them.

@suchismith1993: Is this correct?
