Edit: Sorry, I pasted the wrong output, before. I have corrected it.

This address the CI issue that you were experiencing on Linux, but does not address another one that apparently exists on Windows. Apparently CPLTurnFailureIntoWarning does not exists on Windows (I upgraded to the gisinternals.com GDAL 2.4.3 binary distribution and the function seems not to be there):

cc -Wall -Werror -Os -g com_azavea_gdal_GDALWarp.obj bindings.obj tokens.obj errorcodes.obj -L/windows/gdal/lib -lgdal_i -lstdc++ -lpthread -lws2_32 -shared -o gdalwarp_bindings.dll
bindings.obj: In function `locked_dataset::open()':
/workdir/src/locked_dataset.hpp:706: undefined reference to `CPLTurnFailureIntoWarning'
/workdir/src/locked_dataset.hpp:715: undefined reference to `CPLTurnFailureIntoWarning'
collect2: error: ld returned 1 exit status
Makefile:31: recipe for target 'gdalwarp_bindings.dll' failed
make: *** [gdalwarp_bindings.dll] Error 1
make: Leaving directory '/workdir/src'

That behavior should probably be behind a flag anyway, and should only exist on Linux and Macintosh.
