^^^^^^^^^^^^^^^^^^^
I spent a while scratching my head over this one, before noticing this
little message that this is a W=1 build.
Do you think you could make it more obvious that it's a W=1 build?
Ideally it would be in the subject, though maybe there's no space for it
there. If not having it split out from the rest of the text might help,
it's kind of lost there with all the SHAs and so on.
Or I could just learn to read emails from top to bottom rather than
skimming them :)

Thanks for the feedback, we enabled W=1 by default for now, it looks
silly if adding in the subject,
so we have changed the reproduce command to show the option:
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross W=1
ARCH=powerpc
Best Regards,
