Cool. Is that test package built using the chroot with manually
installed
bundled gcc, or with the modified gcc re-bundled and built from the
top
down
as the src.rpms were intended to be built?
rebundled as the srpm was meant to be used.
Awesome. And just now I realized that I no longer have a RSEL6 desktop
system to test this on easily since I rebuilt my Chromebook with RSEL7.
Seems I need to do something about that...
