--- Comment #17 from Jeffrey A. Law <law at redhat dot com> ---
If there's an interest, I could probably create a kickstart for a RHL8 VM
suitable for building GCC 4.9.   But it's a 10+ year old platform of marginal
value at best.

I'd be much more concerned about using cpu_set_t instead of the dynamically
sizing variants.  As Jakub noted cpu_set_t doesn't work with > 1024 processors
and it's been the source of some cross-distro problems as well.  If at all
possible we need to be moving away from using cpu_set_t to the newer APIs.

My recommendation would be to address the RHL8 problem (no cpu_set_t at all) as
efficiently as possible without burning huge amount of time on it.   Then a
separate BZ to track issues around moving away from cpu_set_t to the more
modern interfaces.
