It's confirmed that neither Alpine nor Musl will fix ioctl warnings[1]
that making alpine build to fail and that these warnings are
harmless[2].
sanei_usb.c:4042:34: error: overflow in conversion from 'long unsigned int' to 'int' changes value from '3221771554' to '-1073195742' [-Werror=overflow]

cc1: all warnings being treated as errors

While outstanding issues that cause compiler warnings are being fixed,
continue using Debian 10 (oldstable) rather than Debian 11 (stable) to
build HTML documentation and run "make distcheck".
Specify -Werror in both CFLAGS and CXXFLAGS for all build jobs.
For the updated build targets, temporarily allow the build job to fail
while outstanding issues that cause compiler warnings are being fixed.
The update-upstreams.sh script is kept for the convenience of those who
want or need to use it. It has been slightly modified to provide more
feedback in case of error conditions.
The "mini" build scenario is sufficiently covered by Debian 10 mini.
Considering the Debian 9 is now oldstable, there is not much value in
keeping it around.
It drops the common `compile:` prefix because the web UI ellipsizes
job names. This leads to names that are hard to tell apart when the
prefix is applied.
The archive stage has been renamed to snapshot to differentiate it
more from the release stage. The prepare moniker did not clearly
describe the stage's intent and has been renamed to tarball. The
job names for these stages now reflect the `make` invocations used
in an attempt to be more descriptive.
This uses the updated Debian images which now use codenames instead
of version numbers.
Note that `CFLAGS=-Werror` has been disabled until such time as all
new warnings have been addressed.
They now have to pass a `make distcheck`. The compile stage takes
care of compiler errors/warnings. We are interested in all checks
passing and the source archive being self-consistent.
The mini variant now has everything needed to roll a source tarball.
It also has git installed so we don't need a convoluted find for our
style check anymore.
CI has been using this for a long time. Now that generated files are
no longer in the repository, new clones require autotools already and
adding a git requirement doesn't seem like a big burden.
