Hi
I am seeing build failures since 11 January.
A build I did on 22 December worked fine.
My build procedure and the error are shown below.

./media/Makefile
It's not clear to me whether this a problem with the media_tree code
or the media_build code.
media/Makefile contains this definition
KBUILD_CFLAGS := -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs \
-fno-strict-aliasing -fno-common \
-Werror-implicit-function-declaration \
