Do you see this with really just --cc=clang ? I see these warnings
if I try to use clang with ccache, but I believe that's a ccache bug.
-- PMM
Not /intentionally/ invoking ccache:
../../configure --cc=clang --host-cc=clang --enable-debug
--extra-cflags="-Werror -Wno-unknown-attributes
-Wno-parentheses-equality -Wno-self-assign -Wno-tautological-compare"
But that's because:
which clang
/usr/lib64/ccache/clang
Which is definitely not of my own doing -- seems to be a default in
Fedora 21.
