Is this a sign that nobody has tested 10.1-stable on a 32-bit ppc?

[Jukka Ukkonen]

Find attached a trailing snippet of build time messages
while running buildkernel on a 32 bit ppc (PowerMac G4
Quicksilver).
During the last 2 months or so there have been some changes
to sys/dev/drm2/radeon/radeon_fence.c in 10.1-stable which
now break buildkernel. Previously I had rebuilt the whole
operating system on this ppc platform on Apr 23 and then
the build worked just fine.

Now the whole oddity starts with an announcement...
"cc1: warnings being treated as errors"
and then begin warning messages about implicit declarations
of this and that atomic 64 bit functions and more warnings
about nested extern declarations of those same functions.
I guess that some of the code seen by the compiler was
never intended to be used on a 32 bit ppc system, but those
changes were never actually tested on a 32 bit ppc either.

Has anyone else noticed this?
