But that... worked previously? Is backward compatibility intended to be broken
in this case?

GNU 90 and C99 have different "extern inline" behavior and has been mentioned
for the last 5 or so years now. What changed was defaulting to the C99/C11
behavior rather than the GNU90 behavior.
This is a kernel bug and should be reported/fixed there instead.

The same could be seen for 253.perlbmk and 400.perlbench tests from spec2K/2006
suites
