I suppose this was tested on x86_64 Linux only (in general, this change may cause problems on different platforms).

If I am not wrong:

  • Windows configuration is addressed by config.w32 files, so it should not be affected by the change
  • aix and darwin have their own paths so they should not be impacted either

What else should we consider and how should we address the tests?

we may also enable this only for x86 and x86_64 Linux, but this way, we
most probably will never know the truth about other platforms.
