Comment 3 Andreas K. Hüttel archtester gentoo-dev 2022-01-29 12:46:53 UTC
Sigh. The configure test uses the C preprocessor:

ac_cpp='$CPP $CPPFLAGS'

Seems like the tinderbox also sets CPP (to enforce clang), and that is the one variable not reset yet...

Fixable, but the fix needs careful testing -> new revbump, later
