Hi Team,
This PR is raised from long time.
Can someone review the change

[derekmauro]

I don't understand the purpose of this or why it fixes an issue or even what the issue is. Since AIX is not a supported platform (https://opensource.google/documentation/policies/cplusplus-support) and this complicates the code, I'd rather not accept this as is.

@derekmauro
Even AIX is not supported platform as per link you shared, I see some closed PR related to AIX
https://github.com/abseil/abseil-cpp/pulls?q=AIX

Regarding complexities, can we have separate section for AIX rules like below,
#if AIX
< existing rules + AIX changes>
#else
<existing rules>

[derekmauro]

We sometimes accept PRs for unsupported platforms if they do not complicate the code. This PR introduces unexplained platform specific build flags. It also provides no explanation why it is necessary since everything seemed to be working before. I suspect there is a more generic way of changing the CMake configuration anyway to achieve whatever this PR is meant to achieve.
