Sorry:
Maybe the my copy/paste was less than east to read?
Maybe because mu copy/paste was from a make -j6 in Docker run from Jenkins?
Maybe the problem is cross-compiling with MinGW?

I don't think I can answer that.
I'm building in a Docker container based on an Ubuntu 20.04 image.
This was my configure:
./configure --extra-version=static_win_x86_64_202207191248
--extra-cflags=--static -static -static-libstdc++ -static-libgcc
-DPTW32_STATIC_LIB -D_WIN32_WINNT=0x0600 --extra-libs=-static
-lpthread -lm --pkg-config-flags=--static
--cross-prefix=x86_64-w64-mingw32- --arch=x86_64 --target-os=mingw32
--prefix=/opt/ffbuild --enable-gpl --enable-version3 --enable-nonfree
--disable-ffplay --disable-dxva2 --disable-w32threads --enable-libzimg
--enable-libxml2 --enable-openssl --enable-libfreetype --enable-libsrt

--enable-libvorbis --enable-libopus --enable-libxvid --enable-libvpx
--enable-libfdk-aac --enable-libopenjpeg --enable-libaom
--enable-libx264 --enable-libx265
This was the last attempted compile and the failure again:

I had hoped that if I included `--disable-indev=gdigrab` in my
./configure then I could get around this problem, but it seems not -
the build continues to fail at the same place.
