My apologies!

What's the value of $CONFIG_ARGS that is referenced here
    $ if test -n "$TARGETS"; then ../configure --enable-werror --disable-docs $CONFIGURE_ARGS --target-list="$TARGETS" ; else ../configure --enable-werror --disable-docs $CONFIGURE_ARGS ; fi || { cat config.log meson-logs/meson-log.txt && exit 1; }

When I configure with
    ../configure --enable-werror --cc=clang --disable-docs --target-list=hexagon-linux-user
I get -Wno-unused-function added to the compiler command line, so I don't see the error.


Both were introduced in patch 22/26.  Should I fix this by respinning the series or sending a single patch?

Ah, looks like it's the version of glib on your system.  The flag gets added in 
configure beneath:

# Silence clang warnings triggered by glib < 2.57.2

I can cherry-pick a single patch.
